#include <stdio.h>
main()
{
    int i;
    int *pi = &i;
    scanf("%d", pi);
    printf("%d\n", i+5);
}

                    
Which one of the following statements is TRUE? (A) Compilation fails. (B) Execution results in a run-time error. (C) On execution, the value printed is 5 more than the address of variable i. (D) On execution, the value printed is 5 more than the integer value entered.
