What happens if the following program is compiled in both C and C++?

[answerhappygod]

#include<stdio.h>
struct STRUCT
{
int static a;
};
int main()
{
struct STRUCT s;
return 0;
}
a) The program runs fine and both prints output “HELLO THIS IS STRUCTURE”
b) The program gives an error in case of C but runs perfectly in case of C++
c) The program gives an error in case of C++ but runs perfectly in case of C
d) The program gives an error in case of both C and C++
