] | B | The crossing moment starts when the head of first compartment of two trains meet or touch. The process of crossing each other continues till 100 + 200 meter = 300 meter is covered. The speed will be 100km/hour + 200 km/hour = 300 km/hour. 300x1000 meter covered in 3600 seconds. So, 300 meter covered in 3.6 seconds.
