Answer 2

D. Nuclear fusion begins under high pressure.

Step-by-step explanation:

A star is a giant astronomical or celestial object that is comprised of a luminous sphere of plasma, binded together by its own gravitational force.

Some of the examples of stars are;

• Canopus.

• Sun (closest to the Earth)

• Betelgeuse.

• Antares.

• Vega.

Stars are typically made up of two (2) main hot gas, Hydrogen (H) and Helium (He). The chronological order in which the formation of a star occur are;

1. Gravity pulls gas and dust together to form dense cores.

2. A protostar forms as mass increases.

3. Nuclear fusion begins under high pressure.

Hence, the final event that occurs when a star is forming is that nuclear fusion begins under high pressure.
