Till stack doesn't overflow
Answer: Option B
Explanation:
A call stack or function stack is used for several related purposes, but the main reason for having one is to keep track of the point to which each active subroutine should return control when it finishes executing.
A stack overflow occurs when too much memory is used on the call stack.
Here function main() is called repeatedly and its return address is stored in the stack. After stack memory is full. It shows stack overflow error.
Can anybody tell how much amount of stack memory is allocated and upon which this depends?

I tried this program on Turbo C++ 4.5 compiler and it gives me error "Cannot call 'main' from within the program in function main()
Also where we used stack here??
Does stack refers to 'Main Memory'?

In the above program we are just printing the statement. we are not declaring any variables and not using any memory. Then why it runs up till stack doesn't overflow?

@Kuldeep Chaudhary
Every called function return value to it's calling function.
Here main() function called by operating system that is main() is called fun and o.s. is calling.
Called fun return 0 after successful execution of program.
If there is any error in execution then it return any nonzero value to it's caller. That value may be +ve or -ve.

In this program you gave main() recursively and it will be print up to infinite times.Is it correct?or not?

I think answer D should state "Until the stack DOES overflow"
