B Correct answer
Explanation

Speed = 900 km / 25 hours = 36 km/hr. Convert to m/s: 36 * (5/18) = 10 m/s.

AI explanation

The required speed is 900 km divided by 25 hours, which equals 36 kmph. To convert this to meters per second, multiply by 5 divided by 18. This gives 36 multiplied by 5 divided by 18, yielding the result of 10 meters per second.
