A continuous spectrum shows us that the star Betelgeuse has a lower surface temperature than the Sun. Therefore (with IR = infrared and UV = ultraviolet),

A. Betelgeuse emits more IR and less UV flux than the Sun.

B. Betelgeuse emits more IR and more UV flux than the Sun.

C. Betelgeuse emits less IR and more UV flux than the Sun.

D. Betelgeuse emits less IR and less UV flux than the Sun.
