Options

A. In tail
B. In acrosome
C. In middle piece
D. In head

Answer

To answer the question regarding the occurrence of mitochondria in sperm, we will follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of Sperm**:
- Sperm is composed of three main parts: the head, the middle piece, and the tail.
