Correct Answer
They continue to move randomly at high velocities with no net change in concentration.
Explanation
Dynamic equilibrium means that while the macroscopic properties (like concentration and pressure) remain constant and uniform, the microscopic molecules continue their random, high-speed thermal motion without interruption.
