Consider the following C code:#include int *assignval(int *x, int val) {*x = val;return x;}void main () {int *x = malloc(sizeof(int));if (NULL == x) return;x = assignval (x, 0);if (x) {x = (int *) malloc (sizeof(int));if(NULL == x) return;x = assignval (x, 10);}printf(“%d\n”, *x);free(x);}The code suffers from which one of the following problems:

• A. Compiler error as the return of malloc is not typecast appropriately
• B. Compiler error because the comparison should be made as x == NULL and not as shown
• C. Compiles successfully but execution may result in dangling pointer
• D. Compiles successfully but execution may result in memory leak
