What is the most likely reason that horses and mountain goats have hooves? they have homologous structures because they have a common ancestor. they have analogous structures because they have a common ancestor. these are vestigial structures in both animals because they are not used. these are similar structures due genetic mutations.

Answer is  A. They are homologous structures because they have common ancestors.

Homologous structures are those which are similar in origin but dissimilar in function. The organs are made of the same bone pattern and structure. Origin of hooves in both the animals have same structure but performing different functions as they live in different habitats. The homologous structures represent divergent evolution.

Your best option to this question is letter A. They are homologous structures because they have common ancestors.
