If light from a distant star passes through a gas cloud before being observed on Earth, what will you see?

A$.$ An emission spectrum because the star light will excite atoms and molecules in the gas cloud.

B$.$ A continuous, blackbody spectrum because everything emits as a blackbody.

C$.$ The star's spectrum but with some emission features from excited atoms$/$molecules in its atmosphere.

D$.$ The star's spectrum but with some absorption features from the atoms$/$molecules in the gas cloud.

E$.$ Nothing, because the gas cloud will block all the starlight.
