Which One Is Not A Reserved Keyword In C Language?

Option C) main is the Correct Answer

Main is not a reserved keyword in C. “main” is a commonly used function name in C programs, typically serving as the entry point of the program. While it’s a common convention to use “main” for the program’s entry function, it is not a reserved keyword, and you could technically use a different function name if you prefer, although it’s not recommended for clarity and compatibility reasons.
