Explanation:

• Option A: Nuclear fission is the splitting of a heavy nucleus, while fusion is the combining of light nuclei. So A is incorrect.
• Option B: Nuclear fusion is much harder to control than fission (e.g., fusion reactors are still in development for practical control, while fission reactors are more established in control). So B is incorrect.
• Option C: The sun's heat comes from nuclear fusion (combining hydrogen into helium), not fission. So C is incorrect.
• Option D: Both nuclear fission (used in nuclear power plants) and fusion (powers the sun) release energy, so they can provide energy.

Answer:

D. Both of these processes can provide energy.
