Answer

To solve the question "Which of the following is not under broadly utilitarian reasons for conserving biodiversity?", we need to analyze each option in relation to broadly utilitarian reasons for conserving biodiversity.

### Step-by-Step Solution:

1. **Understand Utilitarian Reasons**:
- Utilitarian reasons for conserving biodiversity can be categorized into two types:
- **Narrow Utilitarian**: These are benefits derived specifically for human use, often related to direct economic gain.
- **Broad Utilitarian**: These encompass general benefits that biodiversity provides to the ecosystem and humanity, which are not strictly for immediate human use.

2. **Analyze Each Option**:
- **Option 1: Pollination**: This is a broad utilitarian reason as it is essential for the reproduction of many plants and supports food production.
- **Option 2: Aesthetic Pleasure**: This is also a broad utilitarian reason because it contributes to human enjoyment and well-being, promoting conservation for beauty and enjoyment.
- **Option 3: Controlling Soil Erosion**: This is a broad utilitarian reason as it helps maintain soil health and prevents land degradation, which benefits ecosystems and agriculture.
- **Option 4: 25% of drugs sold in the market are plant-based**: This is a narrow utilitarian reason because it specifically relates to the economic benefit derived from plants used in pharmaceuticals.

3. **Identify the Correct Answer**:
- Since options 1, 2, and 3 are all broadly utilitarian reasons for conserving biodiversity, and option 4 is the only one that falls under narrow utilitarian reasons, the answer to the question is **Option 4**.

### Final Answer:
**Option 4: 25% of drugs sold in the market are plant-based** is not under broadly utilitarian reasons for conserving biodiversity.
