Answer: Option D
Explanation:
At 3 o’clock, the minute hand is 15 min. spaces apart from the hour hand.
To be coincident, it must gain 15 min. spaces.
55 min. are gained in 60 min.
| 15 min. are gained in | 60 | x 15 | min | = | 16 | 4 | min. | |
| 55 | 11 |
| The hands are coincident at 16 | 4 | min. past 3. |
