Solution
The correct option is C increase; expanding Once the primary fuel of the star is exhausted, the star starts burning higher elements like nitrogen formed in the thermonuclear fusion. This causes the temperature and pressure of the star increases. On doing so, the star expands into a red giant or a super red giant.
