    Answer : Option C

    Explanation :

    First of all for loop have no braces so for loop on have only next line in its body.
    for( ; digit <= 9; )
    digit++;
    After completing for loop digit = 10;
    next statement digit *= 2; i.e digit = digit * 2 = 20;
    next statement digit--; i.e 20-- => 19
    So final value of digit is 19
