Explanation:

Nuclear fusion in a star occurs in the core, where extreme temperature and pressure allow hydrogen atoms to fuse into helium, releasing energy. The radiative zone, corona, and photosphere have different functions (radiation transfer, outer atmosphere, visible surface) and do not host fusion.

Answer:

B. core.
