B. Batesian mimicry
C. Camouflage
D. Warning colouration.

Answer

To solve the question regarding the close resemblance in the appearance of the Monarch Butterfly and the Queen Butterfly, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Organisms**: Recognize that the two butterflies in question are the Monarch Butterfly and the Queen Butterfly.

2. **Understand the Concept of Mimicry**: Mimicry is a phenomenon where one species evolves to resemble another species. This resemblance can serve various purposes, such as avoiding predation.

3. **Analyze the Options**:
- **Option A: Mullerian mimicry** - This occurs when two or more unpalatable species resemble each other, which reinforces the avoidance behavior in predators.
- **Option B: Batesian mimicry** - This occurs when a harmless species mimics a harmful or unpalatable species to avoid predation.
- **Option C: Camouflage** - This is when an organism blends into its environment to avoid detection.
- **Option D: Warning coloration** - This is a strategy where bright colors are used to warn predators that the organism is toxic or unpalatable.

4. **Evaluate the Characteristics of Monarch and Queen Butterflies**: Both the Monarch and Queen butterflies are known to be unpalatable to predators due to their toxic nature. This means they both share a similar warning to predators.

5. **Determine the Correct Answer**: Since both butterflies are unpalatable and resemble each other, they exemplify Mullerian mimicry. This mutual resemblance helps predators learn to avoid both species effectively.

6. **Conclude**: Therefore, the correct answer to the question is **Option A: Mullerian mimicry**.

### Final Answer:
The close resemblance in the appearance of Monarch Butterfly and Queen Butterfly is an example of **Mullerian mimicry**.
