AREEN from BOLTON SCHOOL, Secunderabad

Answer is C as the question says that Sid wakes up at 6:10 a.m., which is 6 hours 10 minutes of morning, next, the question says he takes 40 minutes to get dressed, 10 minutes to eat breakfast and 25 minutes to reach school, which means 45 min+10 min+25 min=80 min=1 hr 20 min. Then, 6:10 a.m.+1 hr 20 min=7:30 a.m.
