What will be the output of the following C code?

#include <stdio.h>
    struct Item
    {
        int s;
        int t;
    };
    void function(struct Item*);
    int main()
    {
        struct Item I = {33, 44};
        function(&I);
    }
    void function(struct Item *ptr)
    {
        printf("%d\n", *ptr->s++);
    }

1. 33
2. Compilation Error
3. 44
4. Garbage value
5. None of these

Correct Option: B

Compilation Error

main.c: In function ‘function’:
main.c:15:24: error: invalid type argument of unary ‘*’ (have ‘int’)
         printf("%d\n", *ptr->s++);
