Explanation:

  • Waving arms helps balance the rotational effects caused by the alternating leg motion during walking.
  • Without arm movement, the body would need additional effort to maintain balance, increasing strain.
  • Thus, arm movement plays a crucial role in stabilizing the body against gravitational effects.

∴ The correct answer is Option 1: Balance the effect of earth's gravity.
