JEE Main 24 February 2021, Shift 2, Physics Q6

Question 6 of 90 in this shift, Physics question 6 of 30, Section A.

On the basis of kinetic theory of gases, the gas exerts pressure because its molecules :

(1)continuously lose their energy till it reaches wall.
(2)continuously stick to the walls of container.
(3)are attracted by the walls of container.
(4)suffer change in momentum when impinge on the walls of container.Official answer
