C Correct answer
Explanation

Total distance to cover is 212 + 188 = 400 meters. Speed is 45 km/h, which is 45 * (5/18) = 12.5 m/s. Time = Distance / Speed = 400 / 12.5 = 32 seconds.

AI explanation

The total distance the train must travel to cross the platform is the sum of its length and the platform's length: 212 m + 188 m = 400 m. The speed of the train in meters per second is 45 multiplied by 5/18, which equals 12.5 m/s. The time taken is the total distance divided by the speed: 400 m divided by 12.5 m/s equals 32 seconds. The train will cross the platform in 32 seconds.
