Which of the following animals have character of both reptiles and mammals:-

Options

A. Monotremes
B. Marsupials
C. Macropus
D. Canis

Answer

To determine which animals have characteristics of both reptiles and mammals, we can analyze the options provided in the question step by step.

### Step-by-Step Solution:

1. **Understand the Characteristics of Reptiles and Mammals**:
- Reptiles are typically characterized by laying eggs, having scales, and being ectothermic (cold-blooded).
- Mammals are characterized by giving live birth (with some exceptions), having fur or hair, and being endothermic (warm-blooded). They also possess mammary glands.

2. **Evaluate the Options**:
- **Option 1: Monotremes**:
- Monotremes are a group of egg-laying mammals. They exhibit characteristics of both reptiles (they lay eggs) and mammals (they have mammary glands and are warm-blooded).
- Therefore, this option fits the criteria of having both reptilian and mammalian characteristics.

- **Option 2: Marsupials**:
- Marsupials give birth to live young, which develop further in a pouch. They do not exhibit reptilian characteristics, so this option is incorrect.

- **Option 3: Macropus** (a genus that includes kangaroos):
- Like marsupials, Macropus also gives live birth and does not have reptilian characteristics. Thus, this option is also incorrect.

- **Option 4: Canis** (the genus that includes dogs):
- Canis also gives live birth and does not share any reptilian characteristics. Therefore, this option is incorrect as well.

3. **Conclusion**:
- The only option that has characteristics of both reptiles and mammals is **Option 1: Monotremes**.

### Final Answer:
The animal that has characteristics of both reptiles and mammals is **Monotremes**.
