Options

B. Clothes protect us from the sun
C. Clothes protect us from the wind
D. Clothes protect us from insect bites

Answer

**Step-by-Step Solution:**

1. **Understanding Skin Color:** The color of our skin is influenced by a pigment called melanin. Melanin is produced by skin cells and determines how dark or fair our skin appears.

2. **Covered vs. Exposed Skin:** The parts of our body that are usually covered by clothing are less exposed to sunlight. In contrast, the parts of our body that are exposed to the sun, such as our arms and face, receive direct sunlight.

3. **Effect of Sunlight on Skin:** When our skin is exposed to sunlight, particularly ultraviolet (UV) rays, it triggers the production of more melanin. This is the body's natural response to protect itself from the harmful effects of UV rays. As melanin production increases, the skin becomes darker.

4. **Less Melanin in Covered Areas:** The areas of our body that are covered by clothing do not receive as much sunlight, which means they produce less melanin. Therefore, these covered areas tend to be fairer in comparison to the exposed areas.

5. **Conclusion:** The reason why the covered parts of our body are usually fairer than the exposed parts is that they are protected from UV rays, resulting in less melanin production and therefore lighter skin color.

**Final Answer:** The covered part of our body is usually fairer than the other parts because they are protected from sunlight, leading to less melanin production.
