b) measure the size of a star
c) measure the diameter of a star

Explanation:

A spectroscope works by analyzing the spectrum of light emitted or absorbed by an object. Each element has a unique spectral fingerprint. By examining the spectrum of light from a star's atmosphere, astronomers can identify the elements present. Measuring the altitude, size, or diameter of a star is not the function of a spectroscope.

D. Identify elements in the atmosphere of a star
