The correct option is B 10:37
Here the hour hand is in between 9 and 10, very close to 9. So hour hand will be written as 9 and minute hand is 2 divisions after 1, which means (1 * 5) + 2 = 7. So the time shown in tower clock is 9:07.
Now after 1 hour, the hour will be (9+1) = 10. And after 30 minutes, the minutes will be (7+30) = 37. Hence after 1 hour and 30 minutes, the time will be 10:37.
