B Correct answer
Explanation

Quasars cannot be the exploding star in our galaxy as they are the centers of other galaxies , most distant object from earth . Quasars have nothing common with regular stars , only they are the galaxies of stars.

The Big Bang Theory explains:

  1. the beginning of life

  2. origin of the universe

  3. law of Gravity

  4. why the universe was created
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

We know that the universe consists of stars and their respective planetary systems. 

As per the Big Bang Theory, at the beginning of the universe, there was a huge mass of matter. This mass exploded and got broken up into millions of fragments. These fragments became stars. Some parts of these stars got detached from them and cooled down to form planets.
This is how the Universe was created. 

The beginning of life can be explained only after the beginning of the universe and the earth.

The law of gravity explains the mild force of attraction between any two objects. That is the reason why objects fall on earth. It has nothing to do with The Big Bang Theory.
