What term is used to indicate a characteristic that is shared and inherited from a common ancestor?

The question is incomplete as it does not have the options which are:

A) ancestral trait

B) analogous trait

C) homologous trait

D) derived trait

Homologous trait

Explanation:

A homologous trait refers to a trait which is derived from a common ancestor in different species present on the Earth.

The homologous trait is formed as the result of the divergent evolution or a type of evolution in which an organism has diverged to form a different organism.  

Since the trait diverges as well as derived from a common ancestor the trait is known to be shared among species and these traits either play the same role or not in different organisms but they resemble each other.

Thus, Homologous trait is correct.
