Why does the quantity of helium found in the universe support the big bang theory? a. the amount found matches the amount that is necessary to prove quantization of light and matter. b. the amount found matches the amount of mass needed so that the universe can continue to expand. c. the amount found matches the amount required for equivalence between mass and energy. d. the amount found matches the amount predicted to have been created through nucleosynthesis.

The correct option is D.
The big bang theory is the scientific theory that explains how the universe came to exist. The theory explains how the universe expanded due to high temperature and density. Scientists believed that the first nuclei were formed few minutes after the bing bang occurred via a process called bing bang nucloesynthesis. During this process helium and hydrogen were formed and the amount of helium found correspond to the amount predicted by scientists.
