Consider the following program, where are x, y and z are stored in main memory partition?

A. x is stored on the heap memory partition, y is stored on the global partition and z is stored on stack partition. 

B. x, y and z variables are stored on the stack partition. 

C. x is stored on the heap memory, y and z variables are stored on stack partition. 

D. x and y are stored on the heap memory partition and z is stored on stack partition.

int y; int main () { int z = 0; int *x = int * malloc( sizeof (int)); }
