  • ✓
    The acceleration of $S$ is always directed towards the centre of the earth.
  • B
    The angular momentum of $S$ about the centre of the earth changes in direction but its magnitude remains constant.
  • C
    The total energy of $S$ varies periodically with time.
  • D
    The linear momentum of $S$ remains constant in magnitude.
✓

Answer

Correct option: A.
The acceleration of $S$ is always directed towards the centre of the earth.
