What does 'extern' keyword indicate when used with a const variable?

The variable is defined externally
External linkage
No storage is allocated
The variable is a constant expression

The correct answer is: External linkage

The 'extern' keyword with a const variable indicates external linkage. This means that the variable can be used and accessed from other files. Choice A is incorrect because the 'extern' keyword does not necessarily mean that the variable is defined externally, it just indicates external linkage. Choice C is incorrect because storage is still allocated for the variable, even if it has external linkage. Choice D is incorrect because a const variable with the 'extern' keyword is not necessarily a constant expression, it just has external linkage.
