What is the difference between fission and fusion?

A) During fission, a larger nucleus is formed from smaller nuclei. During fusion, a larger nucleus is formed from individual particles.

B) During fission, a larger nucleus is broken down into smaller nuclei. During fusion, smaller nuclei are joined to create a larger nucleus.

C) Fission produces large amounts of energy from a very large mass, but fusion produces small amounts of energy from a very small mass.

B) During fission, a larger nucleus is broken down into smaller nuclei. During fusion, smaller nuclei are joined to create a larger nucleus.

This is the correct difference between fission and fusion. In fission, the nucleus of an atom splits into smaller nuclei, releasing a large amount of energy. In fusion, smaller nuclei combine to form a larger nucleus, also releasing a significant amount of energy.
