In frog, RBCs are

Options

A. Nucleated and biconcave
B. Enucleated and biconvex
C. Nucleated and biconvex
D. Non-nucleated and biconcave

Explanation

**Step-by-Step Solution:**

1. **Understand the Question:** The question asks about the characteristics of red blood cells (RBCs) in frogs. Specifically, it inquires whether they are nucleated or non-nucleated and what their shape is.

2. **Identify the Options:** The options provided are:
- A) Nucleated and biconcave
- B) Enucleated and biconvex
- C) Nucleated and biconvex
- D) Non-nucleated and biconcave

3. **Research Frog RBC Characteristics:**
- In frogs, the red blood cells are known to be **nucleated**. This is a key difference from human RBCs, which are **enucleated** (lack a nucleus).
- The shape of frog RBCs is typically described as **biconvex**, which means they are oval-shaped and bulge outward on both sides.

4. **Analyze Each Option:**
- **Option A:** Nucleated and biconcave - Incorrect. While they are nucleated, they are not biconcave.
- **Option B:** Enucleated and biconvex - Incorrect. Frog RBCs are nucleated, not enucleated.
- **Option C:** Nucleated and biconvex - Correct. This matches the characteristics of frog RBCs.
- **Option D:** Non-nucleated and biconcave - Incorrect. They are nucleated and not biconcave.

5. **Conclusion:** Based on the analysis, the correct answer is **Option C: Nucleated and biconvex**.
