Answer :
Approximate Surface Temperature of an F Star is7000 K. Therefore, the correct option is C.
An important astronomy tool, the Hertzsprung–Russell (H–R) diagram, plots stars according to their brightness (vertical axis) and surface temperature (horizontal axis). Stars in the spectral class known as F stars have temperatures between 6000 and 7500 K. These stars are cooler than A stars but hotter than G stars, which includes our Sun.
The surface temperature of an F star is typically between 7000 and 8000 K. By highlighting important relationships between the temperature, luminosity, and evolutionary stages of stars in the vast cosmic environment, the H-R diagram helps astronomers classify and understand stars.
Therefore, the correct option is C.
