C Correct answer
Explanation

To find the time for a train to cross a pole, we use the formula time = distance/speed. The train's length (350m) is the distance it must travel to completely pass the pole. Dividing 350m by 70 m/s gives 5 seconds. Option D 'Data inadequate' would only be correct if we were missing a required value.
