Solution

The correct option is A $3 : 30$
Detailed step-by-step solution:
Time in the clock when he started $=$ Quarter past $3$
Quarter past $= 15$ minutes past
So, the time is $15$ minutes past $3 = 3 : 15$
Time needed for $1$ song $= 5$ minutes
Time needed for $3$ songs time $= 5 + 5 + 5 = 15$ minutes
So, the time after $3$ songs is $15$ minutes more than $3 : 15.$
For every $5$ minutes, the minute hand will point to the next number.
So, after $15$ minutes the minute hand will point to $6.$

Therefore, the time will be $3 : 30.$
