Which statement is true about the evidence for the Big Bang Theory?

A. Amount of cosmic microwave background radiation is constant, implying contraction.

B. Most distant stars are moving away at faster speeds than those closer.

C. Amount of cosmic microwave background radiation fluctuates, implying expansion.

D. Most distant stars are moving away at slower speeds than those closer

"Amount of cosmic microwave background radiation fluctuates, implying expansion" statement is true about the evidence for the Big Bang Theory.

Option C

Explanation:

The Cosmic Microwave Backgrounds (CMB) are assumed to be the Big Bang residual radiation, or the moment the universe started. As this theory goes, it suffered swift fluctuation and expansion when the universes were raised. Although the universe continues to expand and the rate of expansion is different based on where you live.

The universe began 13.8 billion years earlier, and the CMB dates back approximately 400,000 years after the big bang. Maybe because its temperature in the initial stages of the universe, when it was just one hundred millionth the size it is currently. According to NASA it was severe: 273 million degrees above absolute zero.
