The correct answers are option A.) "CMB radiation and a very early form of helium were discovered" and option C.) "Redshift of distant stars and galaxies indicate the universe continues to expand". The big bang theory states that the origin of the universe as we know it is the result of the expansion from a very high-density and high-temperature state. Scientific evidence that support this theory are: Cosmic Microwave Background (CMB) radiation as is thought to be leftover radiation from the original explosion because it spreads uniformly in the universe; a very early form of helium, as helium is one of the first elements formed after the big bang and; a redshift in light observed in the Hubble that indicates that the objects are moving away from the observers.
