Answer: A) an abnormally large number of collagen fibers and relatively few blood vessels at the repair site
Explanation:
The scar tissues are the thick fibrous tissues typically the collagen fiber that have the role of replacement of healthy tissues after the injury has taken place to initiate the recovery process.
The scars are produced as a biological process at the site of wound repair on the skin. The scar develops on the superficial surface of the skin due to external injury. It is a natural healing process.
There are few blood vessels that can be found at the site of repair along with the collagen fibers.
