Answer: B -The stress is usually applied to align fibers in proliferative phase.

In the proliferative phase, the collagen deposits in a random alignment. When stress is given, such as by deep friction massage, the fibers tend to align.
The inflammatory stage usually begins at the time of injury and ends after 3 - 5 days.
In the maturation phase, the scar has already been formed. Therefore, there is no use of stress being applied.
