The two observations of cosmic microwave background radiation that support the Big Bang theory are:

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.

These observations are significant because they indicate the uniformity and pervasiveness of the radiation, which is a remnant from the hot, dense state of the early universe, consistent with the predictions of the Big Bang theory.
