Solution

The correct option is C Outgrowth of secondary tissue over wounds.
Woody tissues respond to injury by forming a callus, which consists of a mass of undifferentiated cells arising from cell division near the wound surface. Over time, cork encroaches from the area surrounding the wound, and may completely cover it. This structure is called as the knot.
