Ovum receives the sperm in the region of

Options

A. Animal pole
B. Vegetal pole
C. Equator
D. Pigmented area.

Explanation

To answer the question "Ovum receives the sperm in the region of," we need to analyze the options provided and understand the structure of the ovum.

### Step-by-Step Solution:

1. **Understanding the Ovum Structure**: The ovum, or egg cell, has distinct regions known as the animal pole and the vegetative pole. The animal pole is where the nucleus is located and is more metabolically active.

**Hint**: Remember that the ovum has two distinct poles that serve different functions.

2. **Identifying the Poles**: The animal pole is characterized by a higher concentration of cytoplasm and is where the nucleus is present. The vegetative pole, on the other hand, has less active cytoplasm and is primarily involved in nutrient storage.

**Hint**: Think about which pole is more likely to be involved in fertilization due to its activity level.

3. **Sperm Entry Point**: During fertilization, the sperm penetrates the ovum at the animal pole. This is because the sperm's nucleus needs to fuse with the ovum's nucleus, which is located at the animal pole.

**Hint**: Consider where the nucleus of the ovum is located when determining where fertilization occurs.

4. **Conclusion**: Based on the understanding of the ovum's structure and the process of fertilization, we conclude that the ovum receives the sperm at the animal pole.

**Final Answer**: The correct answer is **A. Animal pole**.
