The "C" in ACID stands for Consistency. This property ensures that all database transactions must follow rules and constraints defined in the database schema, maintaining data validity and integrity before and after each transaction.

Heap Sort is the ideal choice for implementing a priority queue. It has a time complexity of O(n log n), making it efficient for maintaining a priority queue structure. Selection Sort, Bubble Sort, and Merge Sort have higher time complexities and are less suitable for priority queue operations.

Option 1 outlines the initial steps of a post-mortem analysis, including forensic analysis, root cause identification, and impact assessment, which are crucial for understanding the breach. Option 2 mentions additional security measures but focuses more on prevention rather than post-incident analysis. Option 3 includes general security measures but lacks specific actions for analyzing the breach. Option 4 involves law enforcement collaboration and incident response, which are important but come after the initial analysis phase.

Dependency Injection in Angular is a design pattern used to manage the components' dependencies. It allows for easy communication between components by injecting the required dependencies directly into them.

In JavaScript, the break statement is used to exit from a loop prematurely. When the break statement is encountered inside a loop, the loop immediately stops executing, and control is transferred to the statement immediately following the loop. This is commonly used to exit a loop based on a certain condition without completing all iterations. Understanding control flow statements like break is essential for writing efficient and structured code in JavaScript.

The correct option is "Transmission Control Protocol." TCP stands for Transmission Control Protocol, which is one of the core protocols in the TCP/IP suite. It provides reliable, connection-oriented communication between devices over a network. TCP ensures data integrity, sequencing, and flow control during data transmission, making it a fundamental protocol for applications that require reliable data delivery.

Continuous Integration (CI) is a practice in Agile development where code changes are merged frequently into a shared repository. The primary goal is to detect integration issues early. CI involves automating tests and builds to ensure code quality and facilitate collaboration among team members. It plays a vital role in Agile by ensuring regular feedback, reducing integration problems, and promoting a more streamlined and efficient development process.

The Factory Method pattern deals with creating instances of a single type of object, providing a method in a class for this purpose. On the other hand, the Abstract Factory pattern creates families of related objects without specifying their concrete classes.

Lazy Loading is a technique in Angular that defers the loading of modules until they are required, which can significantly improve the initial load time and overall performance of an Angular application. While Dependency Injection, Routing, and Components are important features in Angular, Lazy Loading specifically addresses the optimization of loading modules, making it the correct option for this question.

The correct option is "IP." In the TCP/IP protocol suite, the Internet Protocol (IP) is responsible for handling the fragmentation and reassembly of packets. IP breaks large packets into smaller fragments for transmission across networks with different maximum transmission unit (MTU) sizes and reassembles them at the destination. ICMP (Option 1) is used for error reporting and network diagnostics. ARP (Option 2) resolves IP addresses to MAC addresses. TCP (Option 4) is a transport layer protocol for reliable, connection-oriented communication.
