Consider the following statements. Select the correct option.
I. The very common argument about the origin of the universe is the Big Bang theory.
II. It is also termed as Expanding Universe Hypothesis since universe is expanding by accelerating speed.
- I only
- II only
- Both a and b
- None of the above
Hint:
Big band theory explains the formation of universe.
The correct answer is: Both a and b
The most agreed-upon theory of how the universe was formed is the Big Bang theory. Hence, statement I is true.
The Big Bang theory also highlights that the universe is constantly expanding and hence it is also termed as Expanding Universe Hypothesis. Hence, statement II is also true.
Therefore, both statements I and II are true.
