Our theory of the universe was confirmed by the discovery of:
A
fusion.
B
cosmic microwave background radiation.
C
the Andromeda galaxy.
D
the Doppler effect.
Explanation: 

Detailed explanation-1: -The Big Bang theory predicts that the early universe was a very hot place and that as it expands, the gas within it cools. Thus the universe should be filled with radiation that is literally the remnant heat left over from the Big Bang, called the “cosmic microwave background", or CMB.

Detailed explanation-2: -The Cosmic Microwave Background (CMB) is the cooled remnant of the first light that could ever travel freely throughout the Universe. This ‘fossil’ radiation, the furthest that any telescope can see, was released soon after the ‘Big Bang’. Scientists consider it as an echo or ‘shockwave’ of the Big Bang.

Detailed explanation-3: -Fifty years ago today, two astronomers made a discovery that forever changed our understanding of the universe. On May 20, 1964, American radio astronomers Robert Wilson and Arno Penzias were working at the 50-foot-long Horn Antenna in Holmdel, New Jersey, at what was then Bell Telephone Laboratories.
