The correct option is A Origin of Universe
A
lot of evidence and information is gathered by the scientists about the
Universe. They used this information to develop a theory called the Big Bang
Theory. This theory explains the origin
of Universe. This theory states that about 13.7 billion years ago, all the
matter in the Universe was concentrated into a single incredibly tiny point.
This tiny point began to enlarge rapidly in a hot explosion, and it is still
expanding today. All the galaxies are moving away from us is the evidence for
the Big Bang theory.
