A Correct answer
Explanation

Weight on the moon is approximately 1/6th of weight on Earth because moon's gravitational acceleration (g_moon ≈ 1.62 m/s²) is about 1/6th of Earth's (g_earth ≈ 9.81 m/s²). A 12 kg weight on Earth would weigh approximately 12 × (1/6) = 2 kg on the moon. Note: the question uses 'kg' for weight when it should use 'N' for force - mass (12 kg) remains constant.
