Answer

To answer the question "Covering of heart is called," follow these steps:

### Step-by-Step Solution:

1. **Identify the Question**: The question asks for the name of the covering of the heart.

2. **Consider the Options**: The options provided are:
- A) Pericardium
- B) Peritoneum
- C) Perineurium
- D) Periosteum

3. **Analyze Each Option**:
- **Pericardium**: This is known to be the double-layered membrane that surrounds the heart. It consists of an outer layer (parietal pericardium) and an inner layer (visceral pericardium). The space between these layers contains pericardial fluid, which reduces friction as the heart beats.
- **Peritoneum**: This is the membrane that lines the abdominal cavity and covers the abdominal organs. It is not related to the heart.
- **Perineurium**: This is the protective sheath surrounding nerve fascicles in the nervous system. It does not pertain to the heart.
- **Periosteum**: This is the membrane that covers the outer surface of bones. Again, it is unrelated to the heart.

4. **Select the Correct Answer**: Based on the analysis, the correct answer is **A) Pericardium**.

5. **Conclusion**: The covering of the heart is called the pericardium, which serves to protect the heart and reduce friction during its movements.
