Which of the following gases is/are present in the fuel obtained after coal gasification?

想請問各位大神，這題為什麼是D🙇🏻‍♀️ （ratio:比例；collision:碰撞）

9-10. You have two samples of the same gas in the same size container, with the same pressure. The gas in the first container has a kelvin ternperature four times that of the gas in the other container, 4T 1 to T 10. The ratio of number of collisions with the wall in the first container compared to that in the second is (a) 1:1, (b) 4:1, ()1:4,(d) 2:1, (e) 1:2. 273

求詳解謝謝各位🙏
