Question

during a fusion explosion, how are light elements produced from heavy elements?
a supernova explosions and star mergers
b star mergers solely
c stellar explosions solely

Explanation:

Supernova explosions and star mergers are significant astrophysical events. During supernova explosions, the extreme conditions can lead to nuclear reactions that produce various elements. Star mergers also involve intense physical processes. Both these phenomena play crucial roles in the production of elements in the universe. Stellar explosions (which can be a type of supernova) alone or star mergers alone are not sufficient to explain the production of light elements from heavy elements as comprehensively as the combination of both.

Answer:

A. Supernova explosions and star mergers
