    Answer : Option C

    Explanation :

    Time from 5 am. On a day to 10 pm. on 4th day = 89 hours. 
    Now 23 hrs 44 min. of this clock = 24 hours of correct clock 
    365/15 hrs of this clock = 24 hours of correct clock 
    89 hrs of this clock = ( 24 * 15/356 * 89) hrs of correct clock
    = 90 hrs of correct clock. 
    So, the correct time is 11 pm.
