Compared with the peak wavelength given off by the Sun, what is the peak wavelength given off by a hotter star?

This is the anwser sry I didn't anwser my self

Option A

Explanation:

The peak wavelength of a star can be found using Wien's displacement law:

where

b is the Wien's displacement constant

T is the surface temperature of the star

We can see that the peak wavelength is inversely proportional to the temperature: so, a star which is hotter then the sun will have shorter a wavelength.
