I hope this helps, feel free to ask any questions you may have
The answer is B. they embody the idea of descent with modification.

Contracture develops when normally elastic connective tissue are replaced with nonelastic fibrous tissues.
Contracture is the prolonged state of shortening or tightened tissue. Contracture develops when the normally stretchy tissues are replaced by non stretchy fiber-like tissue.
