Question

Which of the following is the correct sequence in the life cycle of a star like the Sun?

A.

Protostar →White Dwarf →Red Giant →Main Sequence

B.

Nebula Red →Giant Main Sequence →White Dwarf

C.

Main Sequence   →Red Giant →White Dwarf

D.

Red Giant →Protostar→ White Dwarf

Correct option is C

The correct answer is (C) Main Sequence → Red Giant → White Dwarf

Explanation:
• A star like the Sun begins as a main sequence star, where it fuses hydrogen into helium.
• After exhausting hydrogen, it expands into a red giant, burning helium in its core.
• Finally, it sheds its outer layers, leaving behind a white dwarf, the dense remnant core.

Information Booster:
• The Sun is currently in the main sequence stage.
• White dwarfs are composed mainly of carbon and oxygen.
• After the white dwarf stage, it slowly cools into a black dwarf (theoretical, not yet observed).
• The Sun will reach the red giant stage in about 5 billion years.
• The nebular stage precedes the main sequence phase in stellar formation.
