Options

A. Mutation
B. anthropologenic action
C. industrial pollution
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 correct.

### Step-by-Step Solution:

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

2. **Evaluating the Options**:
- **Option 1: Mutation**:
- Mutation refers to a change in the DNA sequence of an organism. While mutations can lead to various adaptations over time, they are not an immediate response that animals can take to avoid detection by predators. Therefore, this option is incorrect.

- **Option 2: Anthropogenic Action**:
- Anthropogenic actions are those caused by human activities. This does not relate to how animals avoid detection by predators. Thus, this option is also incorrect.

- **Option 3: Industrial Pollution**:
- Industrial pollution refers to the contamination of the environment due to industrial activities. Like anthropogenic actions, this does not provide a means for animals to avoid detection by predators. Hence, this option is incorrect as well.

- **Option 4: Camouflage**:
- Camouflage, also known as cryptic coloration, is a strategy used by some animals to blend in with their environment. This adaptation allows them to avoid detection by predators, making it a valid response to the question.

3. **Conclusion**: After evaluating all the options, the correct answer is **Option 4: Camouflage**. This adaptation helps animals to avoid being seen by predators by blending into their surroundings.
