Solution

The correct option is B red
By Wien's displacement law, $λ T = b$
Hence, shorter the wavelength, higher will be the temperature and hotter will be the object.
Sun is yellow or orange. So, the colder star should emit longer wavelength. Red has longer wavelength than yellow / orange. So, the given star hence should be red.
