    Answer : Option C

    Explanation :

    Compilers implementing C90 does not allow this but compilers implementing C99 allow it.
    Output:
    $ cc pgm4.c
    pgm4.c: In function 'main':
    pgm4.c:4: error: 'for' loop initial declarations are only allowed in C99 mode
    pgm4.c:4: note: use option -std=c99 or -std=gnu99 to compile your code
