Explanation:

Vestigial structures are remnants with reduced or no function. Convergent structures are similar due to similar environments, not common ancestry. Analogous structures have similar functions but different evolutionary origins. Homologous structures have a common evolutionary origin and similar basic structure. Since vertebrates are related and have the same - basic eye structure, their eyes are homologous structures.

Answer:

D. homologous structures
