Options

A. Reproduction
B. Commercial exploitation
C. Human welfare
D. Both 2 and 3

Answer

### Step-by-Step Solution:

1. **Understanding the Context**: The question discusses hens in captivity, specifically in poultry farms, where they can lay eggs throughout the year.

2. **Identifying the Process**: Normally, hens lay eggs seasonally. However, in poultry farms, they are induced to lay eggs continuously through specific methods.

3. **Hormonal Treatment**: The continuous laying of eggs is achieved through hormonal treatments. This means that the natural reproductive cycle of the hens is manipulated.

4. **Infertility of Eggs**: The eggs produced through this method are typically infertile. This means that they cannot hatch into chicks, as they are not fertilized.

5. **Reproduction vs. Commercial Exploitation**: Since the eggs are infertile, the process does not contribute to reproduction in the traditional sense. Instead, it is a method of commercial exploitation, where the eggs are produced for human consumption.

6. **Human Welfare Aspect**: The eggs produced are beneficial for human welfare as they provide a food source. Therefore, this process serves both commercial purposes and benefits humans.

7. **Conclusion**: The correct answer to the question is that laying eggs in this context is related to both commercial exploitation and human welfare.

### Final Answer:
Laying eggs in captivity (as in poultry farms) is related to commercial exploitation and human welfare (both 2 and 3).
