D. camouflage

Answer

To solve the question "Which of the following responses is taken up by some animals to avoid detection by predators?", we will analyze each option provided and determine which one is the correct response.

### Step-by-Step Solution:

1. **Understanding the Question**:
- The question asks for a response that animals use to avoid being detected by predators. This means we are looking for a defensive adaptation.

2. **Analyzing the Options**:
- **Option A: Mutation**
- Mutation refers to changes in the DNA sequence. While mutations can lead to adaptations over time, they are not a direct response that animals can use immediately to avoid predators. Therefore, this option is incorrect.

- **Option B: Anthropogenic Action**
- Anthropogenic actions are those caused by human activities. While these can impact animals and their habitats, they do not represent a direct response of animals to evade predators. Hence, this option is also incorrect.

- **Option C: Industrial Pollution**
- Industrial pollution refers to harmful substances released into the environment due to industrial activities. This does not relate to how animals defend themselves from predators, making this option incorrect as well.

- **Option D: Camouflage**
- Camouflage, also known as cryptic coloration, is a defensive adaptation that allows animals to blend in with their surroundings. This helps them avoid detection by predators. Many animals, such as owls, toads, and spiders, utilize this strategy effectively. Therefore, this option is correct.

3. **Conclusion**:
- The correct response that some animals take up to avoid detection by predators is **Camouflage**.

### Final Answer:
**Camouflage** is the correct response.
