check answer remaining attempts : 3

Explanation:

Cosmic Microwave Background (CMB) is the after - glow of the Big Bang, a form of remnant radiation left over from the early universe. Stars do not constantly generate CMB. CMB has a nearly uniform temperature across the universe with very tiny fluctuations, and it is not increasing across the universe.

CMB is remnant radiation from the Big Bang.
