how were hydrogen atoms formed?
a. by fusion in large stars
b. through the star cycle
c. through the big bang
d. by fusion in small stars

Explanation:

Hydrogen atoms were formed during the Big - Bang nucleosynthesis. In the early moments of the Big Bang, under extremely high temperatures and densities, protons and neutrons combined to form hydrogen nuclei. Fusion in large and small stars mainly involves the conversion of hydrogen into heavier elements like helium. The star - cycle is related to the life - cycle of stars and the recycling of elements, but not the initial formation of hydrogen atoms.

Answer:

C. Through the big bang
