Solution

The correct option is B Big Bang
Big bang theory is the most accepted cosmological models for the origin of the universe. The heart of this theory is that initially all the matter in this universe was compacted into a very small ball with infinite density and intense temperature. This structure is often referred to as 'Singularity'. About 13.8 billion years ago this singularity underwent a massive explosion or the 'Big Bang' which led to the formation of all the planets, stars and other heavenly bodies later. According to this theory, the development of our universe is not yet completed, it is still expanding.
