All the above

Detailed explanation-1: -Why is the abundance of H/He throughout galaxies an important piece of evidence supporting the Big Bang? H/He were two of the first elements to form following the Big Bang. H/He are highly reactive generating hot spots. H/He are high mass elements formed from supernovae.
Detailed explanation-2: -Helium Abundance. One of the predictions that the Big Bang theory leads to, concerns the abundance by mass of Helium we should see in the universe. The “conditions” during Big Bang Nucleosynthesis were just perfect to create about 25% Helium, 75% Hydrogen, and much less than 1% of everything else.
Detailed explanation-3: -The abundance of chemical elements in the universe is dominated by the large amounts of hydrogen and helium which were produced in the Big Bang. Remaining elements, making up only about 2% of the universe, were largely produced by supernovae and certain red giant stars.
