Can anyone tell me which one is correct or most appropriate answer for code written in C language?

Code1:

#include<stdio.h>

int main()
{
    int i=10, j=20;
    const int *ptr = &i;

    printf("i = %5X", ptr);
    printf("ptr = %d", *ptr);
    ptr = &j;
    printf("j = %5X", ptr);
    printf("ptr = %d", *ptr);
    return 0;
}

Choice:
A. i= FFE2 ptr=12 j=FFE4 ptr=24
B. i= FFE4 ptr=10 j=FFE2 ptr=20

C. i= FFE0 ptr=20 j=FFE1 ptr=30
D. Garbage value

Code2:

#include<stdio.h>

int fun(int **ptr);

int main()
{
    int i=10;
    const int *ptr = &i;

    fun(&ptr);
    return 0;
}

int fun(int **ptr)
{
    int j = 223;
    int *temp = &j;

    printf("Before changing ptr = %5x\n", *ptr);
    const *ptr = temp;
    printf("After changing ptr = %5x\n", *ptr);
    return 0;
}

The answer of above program

Because i dont know much about pointers in C
