Answer

To determine the most important factor to consider when constructing a pig house in tropical countries, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understanding the Environment**: Tropical countries are characterized by high temperatures and humidity levels. Therefore, any structure built in these regions must be able to cope with these conditions.

2. **Evaluating the Options**:
- **Option A: Sunlight**: While sunlight is important for any structure, excessive sunlight can lead to overheating, which is not ideal for pigs.
- **Option B: Air**: Good ventilation is crucial for animal welfare, but it is not the most critical factor when compared to humidity.
- **Option C: Humidity**: This is a significant factor because high humidity can lead to discomfort and health issues in pigs. Proper construction should help manage humidity levels to ensure the pigs remain healthy.
- **Option D: Temperature**: While temperature is important, it is closely related to humidity. High humidity can make temperatures feel hotter, impacting the pigs' comfort.

3. **Conclusion**: Given the tropical climate's characteristics, managing humidity is essential for the health and well-being of pigs. Therefore, the most important factor to consider when constructing a pig house in tropical countries is **Option C: Humidity**.

### Final Answer:
The most important factor to be taken into consideration while constructing a pig house particularly in tropical countries is **Humidity (Option C)**.
