Question

Quizplus · Accepted Answer

All three options given (A, B, and C) provide support for the big bang theory. Option A, the observation that all galaxies are moving away from one another, implies that the universe is expanding from a point of origin, which supports the idea of a big bang. Option B, the calculation of primordial nucleosynthesis, refers to the formation of elements in the early universe, such as helium, and the fact that the calculated abundance of these elements aligns with the theory is another piece of evidence. Option C, the cosmic background radiation, refers to the leftover energy from the big bang and its calculation aligning with theory provides additional support for the big bang. Thus, all three options support the big bang theory, making the best choice D.
