The correct inference to make from the spectrum readings is:

• There is a red shift, which means that the star is moving away from the sun.

A red shift indicates that the wavelengths of light are being stretched, which occurs when an object is moving away from the observer. Conversely, a blue shift indicates that the wavelengths are being compressed, which happens when an object is moving toward the observer.
