Solution
The correct option is B Big-bang theory
The universe was born with the Big Bang as an unimaginably hot, dense point. When the universe was just 10-34 of a second or so old that is, a hundredth of a billionth of a trillionth of a trillionth of a second in age it experienced an incredible burst of expansion known as inflation, in which space itself expanded faster than the speed of light. During this period, the universe doubled in size at least 90 times, going from subatomic-sized to golf-ball-sized almost instantaneously. Thus, option B is correct.
The steady-state theory is a view that the universe is always expanding but maintaining a constant average density, matter being continuously created to form new stars and galaxies at the same rate that old ones become unobservable as a consequence of their increasing distance and velocity of recession. Thus, option A is wrong.
In 1953, Stanley L. Miller and Harold C. Urey, was working at the University of Chicago, conducted an experiment which would change the approach of scientific investigation into the origin of life. Their experiment is not related to origin of universe. Thus, option C is wrong.
According to Oparin Haldane theory, life evolved in the oceans during a period when the atmosphere was reducing - containing H2, H2O, NH3, CH4, and CO2, but no free O2. Thus, option D is wrong.
