**Core Concept**
Scurvy is a disease caused by a deficiency of a specific vitamin that plays a crucial role in collagen synthesis, wound healing, and iron absorption. This vitamin is essential for maintaining healthy connective tissue, blood vessels, and bone.

**Why the Correct Answer is Right**
The correct answer is **Vitamin C**. Vitamin C is a crucial cofactor for the enzyme prolyl hydroxylase, which is necessary for the stabilization of collagen molecules. Without sufficient vitamin C, collagen synthesis is impaired, leading to the characteristic symptoms of scurvy, such as fatigue, malaise, and bleeding gums. Vitamin C also plays a role in the conversion of folic acid to its active form, which is necessary for iron absorption and utilization.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because Vitamin B12 is a different vitamin that plays a crucial role in DNA synthesis and energy production, but it is not directly related to scurvy.

**Option B:** This option is incorrect because Vitamin E is an antioxidant that protects cells from damage, but it is not directly involved in collagen synthesis or iron absorption.

**Option C:** This option is incorrect because Vitamin K is necessary for blood clotting, but it is not related to the development of scurvy.

**Clinical Pearl / High-Yield Fact**
It's essential to note that scurvy can be prevented and treated with dietary supplementation of vitamin C, and it's a common condition in individuals with a restricted diet or those who are malnourished.

**Correct Answer:** C. Vitamin C.
