Explanation:

First Question (Our sun is......):

• A white dwarf is a stellar remnant, not what the Sun currently is.
• A yellow giant is a later stage in stellar evolution; the Sun is not a giant yet.
• The Sun is in the main sequence stage of its life cycle, where it fuses hydrogen into helium in its core.
• The Sun is composed of plasma (hydrogen, helium, etc.), not dark matter. So the correct option is "a main sequence star".

• An ATV is an all - terrain vehicle, unrelated to Polaris (the star).
• The North Pole is a geographic location, not a name for Polaris.
• Earth’s magnetic field is a magnetic phenomenon, not related to the star Polaris.
• Polaris is commonly known as the North Star, as it is located nearly at the Earth's North Celestial Pole.

Answer:

C. a main sequence star
