Why can deciding evolutionary relationships only by external similarity be wrong?

Answer and explanation

Correct answer: Analogous organs may appear similar in function while having different origins

External resemblance alone is not reliable evidence of close evolutionary relationship because unrelated groups can develop similar features when they face similar environmental demands. These are analogous similarities, produced by convergent evolution. Scientists therefore also compare internal anatomy, embryology, fossils and molecular evidence. Option A is correct because similar outward function may hide different origins. B and C are plainly false, while D wrongly treats every resemblance as proof of common ancestry.
