Explanation

To solve the question "Which of the following is not an example of in situ conservation?", we can follow these steps:

### Step 1: Understand the Concepts
- **In situ conservation** refers to the conservation of species in their natural habitats. This includes protecting ecosystems and natural environments.
- **Ex situ conservation** involves the conservation of species outside their natural habitats, such as in zoos or botanical gardens.

### Step 2: Analyze the Options
- **Option A: Biosphere Reserves** - These are areas designated to protect biodiversity and ecosystems, making them an example of in situ conservation.
- **Option B: National Parks** - These are protected areas that conserve the entire ecosystem, thus they are also an example of in situ conservation.
- **Option C: Wildlife Sanctuaries** - These areas protect specific flora and fauna within their natural habitats, qualifying them as in situ conservation as well.
- **Option D: Zoological Parks** - These are facilities where animals are kept in enclosures for public display and education, which means they are an example of ex situ conservation.

### Step 3: Identify the Correct Answer
From the analysis, **Option D: Zoological Parks** is the only option that does not represent in situ conservation, as it involves the conservation of species outside their natural habitats.

### Final Answer
The correct answer is **Option D: Zoological Parks**.
