In a pendulum's motion, energy conversions take place as it moves between potential energy and kinetic energy.

- At **point A**, the pendulum is at its highest point, where it has maximum potential energy and minimal kinetic energy. Here, potential energy is at its peak.
- As it swings down to **point B**, potential energy converts into kinetic energy, reaching maximum kinetic energy at the lowest point.
- At **point C**, as the pendulum rises again, kinetic energy converts back into potential energy.

Based on this understanding, the energy conversions occur at:

- **Point A** (potential energy to kinetic energy as it moves down).
- **Point B** (kinetic energy to potential energy as it moves up).
- **Point C** (potential energy increases again).

Considering all the energy conversions that take place during the motion of the pendulum, the correct answer would be:

**D) Both points A and C** (because energy conversions from kinetic to potential energy occur at both points A and C).
