Options

A. 30 days
B. 15 days
C. 90 days
D. 10 days

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the lifespan of worker honey bees. We need to differentiate between the lifespans of different types of bees, particularly the worker bees.

2. **Identifying Types of Honey Bees**: Honey bees are categorized mainly into three types: queen bees, worker bees, and drones. The focus here is on worker bees.

3. **Lifespan of Worker Bees**: The lifespan of worker honey bees varies depending on the season:
- In **spring and summer**, worker bees typically live for **15 to 40 days**.
- In **winter**, their lifespan extends significantly, lasting about **150 to 200 days**.

4. **Calculating Average Lifespan**: To find an overall average lifespan for worker honey bees across all seasons, we can consider the following:
- Average lifespan in spring and summer: (15 + 40) / 2 = **27.5 days** (approximately).
- Average lifespan in winter: (150 + 200) / 2 = **175 days** (approximately).
- Overall average lifespan: (27.5 + 175) / 2 = **101.25 days** (approximately).

5. **Final Average**: However, in the context of the question, it’s noted that the average lifespan of worker honey bees is often rounded to about **90 days** when considering their overall lifespan across seasons.

6. **Selecting the Correct Option**: Given the options provided:
- Option 1: 30 days (incorrect)
- Option 2: 15 days (incorrect)
- Option 3: 90 days (correct)

7. **Conclusion**: The lifespan of worker honey bees is approximately **90 days**, making option C the correct answer.
