B. proliferation phase

Explanation:

The proliferative phase is one of the stage of wound healing. This is a phase in which new tissues rebuilt over the injury to heal it. The tissues are made up of collagen.

In the proliferative phase the injury contracts and the skin becomes stiff, the muscles becomes rigid thus the body require optimal time to begin the therapeutic exercise. The exercise will improve the motion and flexibility of the body. The new network of blood vessels will cause the granulation of the tissues and provide sufficient nutrients and oxygen for recovery.
