  1. never becomes zero

  2. becomes zero in each turn

  3. becomes zero in equilibrium case

  4. always remains the same

B Correct answer
Explanation

At the extreme positions of its swing (maximum amplitude), a simple pendulum momentarily comes to rest as it changes direction. At this point, its kinetic energy is zero. The kinetic energy then increases as it accelerates toward the lowest point, converting potential energy to kinetic energy.
