A
true
B
false
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -All scarring is composed of the same collagen as the tissue it has replaced, but the composition of the scar tissue, compared to the normal tissue, is different. Scar tissue also lacks elasticity unlike normal tissue which distributes fiber elasticity.

Detailed explanation-2: -Scar tissue (not to be confused with adhesions) replaces normal tissue that is damaged. If you break down you are essentially saying that you are causing a new wound. At its best scar tissue is only 70% as functional as normal tissue. But scar tissue could be functioning at less than 10% of normal tissue.

Detailed explanation-3: -Scars form as part of the body’s healing process. Your body builds tissue to repair damaged skin and close gaps due to an injury. Scars come in all shapes and sizes.

Detailed explanation-4: -In other words, normal skin tissue is constructed of fibres that are oriented randomly to each other, while the very same fibres, in scar tissue, are oriented in a single direction, parallel to each other.
