What will be the output of the following C program code if the file "test.txt" is empty, readable, and exists in the appropriate directory?

#include <stdio.h>
int main() {
    FILE *fp = fopen("test.txt", "r");
    if (fp == NULL) {
        printf("Error\n");
    } else {
        printf("Success\n");
        fclose(fp);
    }
    return 0;
}

• ASuccess
• BNULL
• CGarbage value
• DError
