Does there exist any way to make the command-line arguments available to other functions without passing them as arguments to the function?
Answer: A
Correct answer: Yes
The parameters of main are local to it, but their values need not stay there. The straightforward method is to copy them into file-scope variables at the top of main, after which any function in the translation unit can read them.
Some environments also expose them directly: Turbo C provides the globals _argc and _argv, and several Unix systems have equivalents. Either way the answer is yes, though the portable route is the explicit copy into globals of one's own.
