According to the big bang theory, how did a star form from a cloud of dust and gas?
a)the big bang blew the dust and gas particles together.
b)solar winds blew the dust and gas particles together.
c)magnetism drew the dust and gas particles together.
d)gravity pulled the dust and gas particles together.

Option-(D): Gravity pulled the dust and gas particles together.

Explanation:

The big bang:

We all think of the universe, about it  all started?, what caused the universe, and the formation of different celestial bodies inside the different galaxies. So, for that reason we have a very scientific answer to all of it, which is called as the "The Big Bang theory".  As, all of the universe was once a single entity but at a certain period of time expansion happened and the different celestial bodies were formed i.e the stars, satellites, meteors, the planets.

The formation of Stars:

Stars are big masses of different gases in a very enormous proportion. While, the formation of the different stars is very specific in nature. After the big bang happened the elements or the particles were all scattered in the universe. And through the gravitational pull which existed inside the celestial bodies by means of the stars, they were formed by the gravitational pull present in the space which pulled together the required dust and gaseous particles for the formation of the stars.
