The definition of vestigial organs are rudimentary structures in humans that correspond to a functional structure or organ in an ancestor. Basically the answer is redundant organs present in an organism, which have been functional in the organism's ancestors.

Answer:

The correct answer is c. redundant organs present in an organism, which have been functional in the organism’s ancestors.

Vestigial organ are those which are retained in the evolution however lost their original functions due to change living habits or surroundings of the organisms.

They serve as the evidence of evolution and help in evolutionary studies.
