Scientists are able to study the composition of a star located outside of the Solar System primarily:
**A. by evaluating the different colors of light radiated by the star.**
This method involves analyzing the star's spectrum, which reveals the various wavelengths of light emitted or absorbed by the star. Each element emits or absorbs light at specific wavelengths, allowing scientists to determine the star's composition, temperature, density, and even motion through the Doppler effect.
