The correct statement is:
**D. The stars are made of similar elements.**
Stars that produce similar spectral patterns typically have similar temperatures, which correlates with their elemental composition. Their spectra arise from the absorption lines of specific elements, so similar spectral patterns indicate that the stars have similar elemental abundances. However, they can differ in mass, size, and age despite having similar spectral characteristics.
