The correct option is B 17:35
If the given time is lying within 12:01 am and 12: 59 pm, then there is no change while converting it from 12-hour format to 24-hour format.
If the given time is between 12:59 pm and 12:00 am (midnight), we add 12 to the given time to convert it from 12-hour format to 24-hour format.
Thus, 5:35 pm, which comes between 12:59 pm and 12:00(midnight) reads as 05:35+12:00=17:35 in the 24-hour format.
