Question

our sun is...... *

○ a white dwarf

○ a yellow giant

○ a main sequence star

○ composed of dark matter

Explanation:

• A white dwarf is a stellar remnant, not what the Sun currently is.
• A yellow giant is a later stage of stellar evolution; the Sun is not a giant yet.
• The Sun is in the main sequence phase, where it fuses hydrogen into helium in its core, which matches its current state.
• The Sun is composed of plasma (hydrogen, helium, etc.), not dark matter (dark matter is a hypothetical form of matter not part of stellar composition).

Answer:

C. a main sequence star
