It shows that only simple elements are present in the universe.

It proves that matter must be formed under high temperatures.

Answer 1

The correct response is:

It is the proportion predicted to be present in the early universe.

This is because the Big Bang theory predicts specific ratios of hydrogen and helium produced in the early universe during the process of nucleosynthesis. Observations of the current composition of the universe show that these proportions align with those predictions, providing strong support for the theory.
