    Answer : Option D

    Explanation :

    In this type of problems the formuae is
    (5*x+ or - t)*12/11
    Here x is replaced by the first interval of given time. Here x is 5.
    t is spaces apart Case 1 : (5*x + t) * 12/11
    (5*5 + 3) * 12/1128 * 12/11 = 336/11=  min
    therefore the hands will be 3 min apart at 31 5/11 min past 5. 
    Case 2 :
     (5*x - t) * 12/11(5*5 -3 ) * 12/11 22 *12/11 = 24 min 
    therefore the hands will be 3 min apart at 24 min past 5
