## **Core Concept**
The question tests knowledge of vitamin deficiencies in relation to dietary habits, specifically focusing on carnivores. Vitamin deficiencies can arise from inadequate dietary intake, and certain deficiencies are more prevalent in individuals with restrictive diets, such as those consuming only meat.

## **Why the Correct Answer is Right**
The correct answer, **Taurine**, is a nutrient, not technically a vitamin, but often classified under the broader category of vitamins due to its essentiality for health. Taurine is found predominantly in animal-based foods, particularly in seafood and meat. While not exclusively a vitamin, its deficiency has been noted in conditions where dietary intake is limited to meat, without the inclusion of other nutrient sources. However, the more accurate answer related to vitamins would be **Vitamin C**, as it is well-known that **Vitamin C deficiency (scurvy)** occurs in individuals who do not consume fruits and vegetables but exclusively eat meat.

## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is not provided, but if we consider common vitamin deficiencies, **Vitamin D** deficiency can occur in individuals with limited sun exposure and inadequate dietary intake, not exclusively in carnivores.
- **Option B:** Similarly, this option is not provided, but another vitamin like **Vitamin B12** deficiency can occur in strict vegetarians, not exclusively in carnivores.
- **Option C:** If this option represented **Vitamin C**, it would actually be a strong candidate because **Vitamin C deficiency** does indeed occur in individuals with a diet lacking fruits and vegetables, which could be a subset of carnivores. However, without the specific vitamin listed, we proceed with caution.
- **Option D:** Assuming this is not the correct answer based on the question's framing.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that **Vitamin C deficiency (scurvy)** classically presents with fatigue, malaise, and connective tissue defects, and it exclusively occurs in individuals who do not consume fruits and vegetables. This condition is notably preventable with the inclusion of vitamin C-rich foods in the diet.

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