Suppose you're implementing a command-line tool in Go, and you want to handle different options provided by the user. Which control structure in Go would be the most suitable choice for this scenario?

For handling different options provided by the user in a command-line tool implemented in Go, the switch control structure would be the most suitable choice. The switch statement allows you to evaluate multiple conditions based on the value of an expression and execute the corresponding block of code. This makes it ideal for parsing and handling command-line options efficiently. Unlike if-else statements, which can become cumbersome with multiple options, switch statements offer a cleaner and more concise syntax for managing various cases. Therefore, in this scenario, using switch ensures better readability and maintainability of the code.
