    Answer : Option C

    Explanation :

    The file source.txt contains "Be my friend".

    fseek(fs, 0, SEEK_END); moves the file pointer to the end of the file.

    fseek(fs, -3L, SEEK_CUR); moves the file pointer backward by 3 characters.

    fgets(c, 5, fs); read the file from the current position of the file pointer.

    Hence, it contains the last 3 characters of "Be my friend".

    Therefore, it prints "end".
