In a project involving real-time systems, you notice that different modules use different naming conventions for the same data type. What feature of C can help maintain consistency across modules?

Option A, "Typedef," is the most suitable choice in this context. By using typedef, you can create consistent, user-friendly names for data types, which helps maintain a unified naming convention across modules in a project. This consistency enhances code readability, reduces errors, and simplifies maintenance. Namespaces are not a feature in C, and other options do not directly address naming convention consistency. Understanding how to use typedef effectively is essential for creating a consistent codebase in C.
