**Core Concept**
Ehlers-Danlos syndrome is a group of genetic disorders that affect the body's connective tissue, leading to skin hyperextensibility, joint hypermobility, and tissue fragility. In some cases, it can also cause hypoplasia of limbs and scarring due to poor wound healing.

**Why the Correct Answer is Right**
The correct answer is related to the pathophysiology of Ehlers-Danlos syndrome, which is caused by mutations in genes that code for collagen, a key component of connective tissue. These mutations lead to the production of defective collagen, resulting in fragile skin and poor wound healing. In some cases, this can cause hypoplasia of limbs due to impaired growth and development.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because it does not directly relate to the pathophysiology of Ehlers-Danlos syndrome. While it may cause scarring, it is not the primary cause of hypoplasia of limbs.
* **Option B:** This option is incorrect because it is a different condition that affects the skin, but it does not cause hypoplasia of limbs or scarring due to poor wound healing.
* **Option C:** This option is incorrect because it is a different condition that affects the joints, but it does not cause scarring or hypoplasia of limbs.

**Clinical Pearl / High-Yield Fact**
Ehlers-Danlos syndrome is a classic exam trap that can be remembered by the mnemonic "EDS": Easy bruising, Delayed healing, and Sagging skin. This mnemonic helps to recall the key features of the condition, including hypoplasia of limbs and scarring.

**Correct Answer: C. Ehlers-Danlos syndrome.**
