D. Rat

Answer

To solve the question regarding the type of red blood cells (RBCs) found in different animals, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of RBCs**:
- Red blood cells (RBCs) can vary in shape and structure among different species. In most mammals, RBCs are typically biconcave and enucleated (they lack a nucleus).

2. **Identify the Options**:
- The options provided are:
(a) Camel
(b) Rabbit
(c) Man
(d) Rat

3. **Analyze Each Option**:
- **Camel**: Camels are unique among mammals because they have oval-shaped, biconvex, and nucleated RBCs. This adaptation helps them survive in harsh environments.
- **Rabbit**: Rabbits, like most mammals, have circular, biconcave, and enucleated RBCs.
- **Man**: Humans also have circular, biconcave, and enucleated RBCs.
- **Rat**: Rats, being mammals, similarly possess circular, biconcave, and enucleated RBCs.

4. **Determine the Correct Answer**:
- Since the question asks for the animal that has oval, biconvex, and nucleated RBCs, the only option that fits this description is the camel.

5. **Final Answer**:
- The correct answer is (a) Camel.
