Since void pointer can return any type of pointer, in this problem it returns an integer pointer. Since 0 is null value of integer, the pointer return will be a null pointer.....

It is Null Pointer because, Pointer stores the addresses of another variable but when variable type is not known then it will be (void) and to store address it is consist(*) also,so (void *) and initially it points to 0th address, Means Null.

The Syntax for function definition is
return type function name(data type variable name)
but here the data type is given and the variable name is not given
and there is no return type.so,it is a null pointer.a void pointer is a pointer with return type void.
return type function name(data type variable name)
but here the data type is given and the variable name is not given
and there is no return type.so,it is a null pointer.a void pointer is a pointer with return type void.

void(*) measns void pointer,it means value is nt given or void..
but void(*0)means it point to null value(i.e 0)..therefore null pointer
but void(*0)means it point to null value(i.e 0)..therefore null pointer
