Answer

Brief Explanations:

The Big - Bang theory posits that the universe originated from a hot, dense state and has been expanding and cooling since then. Cosmic microwave background (CMB) radiation is a key piece of evidence for the Big - Bang. The fact that CMB radiation exists uniformly across all areas of the observable universe (Option B) suggests a common origin for the universe. Also, its relatively consistent temperature throughout the observable universe (Option E) indicates that the early universe was in a highly homogeneous state, which is consistent with the Big - Bang model. Option A is incorrect as CMB radiation redshifts but does not increase in mass. Option C is wrong because CMB radiation does not contain all the dark matter necessary to start the Big - Bang. Option D is inaccurate as CMB radiation does not store the same amount of energy as the Big - Bang likely released.

Answer:

B. Cosmic microwave background radiation exists in all areas of the observable universe. E. Cosmic microwave background radiation has a relatively consistent temperature throughout the observable universe.
