Correct option is C
The correct answer is: (c) White Dwarf → Main Sequence → Red Giant
Explanation:
• A star like the Sun begins as a nebula and becomes a protostar, then enters the main sequence stage (hydrogen fusion).
• After exhausting hydrogen, it expands into a red giant.
• The final stage for such stars is a white dwarf, formed after shedding outer layers.
• Option (c) represents the correct later stages in simplified form.
Information Booster:
• Sun’s current stage: Main Sequence, age ~4.6 billion years.
• It will expand into a red giant in ~5 billion years.
• White dwarfs are Earth-sized but extremely dense remnants.
• Fusion stops inside white dwarfs; they gradually cool.
• More massive stars may form neutron stars or black holes instead.
