A
Fully formed and functional
B
Much reduced but functional
C
Much reduced and functionles
D
Fully formed but functionaless
Explanation: 

Detailed explanation-1: -These organs are reduced because of no use over a long period. They become non-functional, and their activity also becomes nil. An example of a vestigial organism is the vermiform appendix.

Detailed explanation-2: -What are Vestigial Organs? Vestigial organs are organs, tissues or cells in a body which are no more functional the way they were in their ancestral form of the trait. It is authentication of evolution and hence, were helpful in explaining adaptation.

Detailed explanation-3: -Vestigial organs are rudimentary anatomical structures that are retained in a species despite having lost their primary ancestral function. These structures often lack an apparent purpose, in contrast to the full functionality of these organs observed in closely related and ancestral species.

Detailed explanation-4: -Vestigial structures are body parts that have lost their use through evolution. Homologous structures are structures that have a common function and suggest common ancestry. Similar embryos suggest that these animals are related and have common ancestors.

Detailed explanation-5: -Examples of vestigial organs in humans usually include the appendix, the coccyx (tail bone), and the tonsils. Body hair, wisdom teeth, nipples on males, nictitating membrane of eye, tonsils are also the vestigial organs of humans.
