What's responsible for preventing the gas giants from collapsing into a star?
a. they're too far from the sun to begin collapsing into a star.
b. their fast rotation rates result in centrifugal force.
c. the sun exerts tidal forces that prevent collapse into a star.
d. their large masses decrease the gravity they experience.

D. Their large masses decrease the gravity they experience
(The gravitation pull is not strong enough to cause the fusion of hydrogen atoms.)

B. Their fast rotation rates result in centrifugal force.

Explanation:

The gas giant has a high mass and great gravitational attraction as that of the terrestrial planet thus has a higher rate of motion results in the generation of a centrifugal force that that ecert is strong enough to influence to protect them from the collapsing into a star. The gas planet thus can escape the collapse or the collision to the star. And the potential difference is the energy that is being generated with the rise of the temperatures. Thus the gas giant is also known as the failed stars.

There can be more freedom for them
