Explanation:

The Hertzsprung - Russell (HR) diagram plots stars based on luminosity and temperature (or spectral class). The Sun is known to lie on the main sequence of the HR diagram, where stars are in the stage of fusing hydrogen into helium in their cores. Giant stars, white dwarf stars, and supergiant stars are in different evolutionary stages or have different characteristics compared to the Sun's current stage.

Answer:

a. Main sequence star
