Explanation:

• Option A: The energy for the body comes from food (like carbohydrates, fats, proteins), not directly as "all energy" from the Sun.
• Option B: The Sun emits ultraviolet radiation. Excessive exposure to UV radiation (especially UV - B and UV - C, though most UV - C is absorbed by the ozone layer) can damage DNA in skin cells, leading to mutations that may cause skin cancer.
• Option C: Oxygen for breathing is mainly produced by photosynthesis in plants (not directly from the Sun as a source of the gas itself).

Answer:

B. ultraviolet radiation that can cause cancer
