Explanation:

- Two trains are moving in the same direction.

- Train speeds are 54 km/h and 92 km/h.

- Train lengths are 400 m and 360 m.

- Relative speed: (92 - 54) km/h = 38 km/h.

- Convert relative speed to m/s: 38 km/h = (38 * 1000) / 3600 m/s = 10.56 m/s.

- Total length to be covered: 400 m + 360 m = 760 m.

- Time taken = Total length / Relative speed = 760 m / 10.56 m/s ˜ 72 seconds.

- Correct Option: Option: 2 - 72 seconds
