Answer:

Homologous structures

Explanation:

Its C

Similar features that originated in a shared ancestor are called Homologous structure. So, the correct option is C.

Homologous structures are defined as structures that have a common basic structure but perform different functions. For example, the forelimbs of reptiles, amphibians and mammals all have a common ancestor but have been variously modified to perform different activities.

Homologous structures share a similar ancestor as they are modified to perform distinct tasks. Like in the above given example, the legs of a crocodile and a mouse have similar bone structure and develop in a similar way.

Thus, similar features that originated in a shared ancestor are called Homologous structure. So, the correct option is C.
