The reason that stars such as the Sun don't collapse from their own self-gravity is D. the outward pressure created by nuclear fusion.
Why don't stars collapse from their gravity?
As a result of nuclear fusion which fuses hydrogen into helium in the cores of stars, there is a lot of energy produced.
This energy exerts an outward pressure on the star that ensures that it does not sink into its own gravity.
In conclusion, option D is correct.
