Answer
A
It remains the same.
B
It decreases slowly.
C
It increases quickly.
D
It decreases rapidly.

Explanation

Heating the bromine raises its temperature. The average kinetic energy of particles is directly related to temperature, so the bromine particles’ average kinetic energy increases. The best choice is “It increases quickly.”
