D. Both A and B

Explanation

To solve the question, we need to analyze the characteristics of each organism mentioned in the paragraph and determine which statement does not hold true for them.

### Step-by-Step Solution:

1. **Identify Organism P**:
- Characteristics: Leathery lips and a big hump on its back.
- Likely candidate: This description fits a camel, which has adaptations for surviving in arid environments.

2. **Identify Organism Q**:
- Characteristics: Thick layer of subcutaneous fat and dense fur covering.
- Likely candidate: This description fits a polar bear, which has adaptations for cold environments.

3. **Identify Organism R**:
- Characteristics: Brightly colored with a long, large, and colorful beak.
- Likely candidate: This description fits a toucan, which is known for its vibrant colors and large beak.

4. **Evaluate Statements**:
- Statement A: Organism P excretes very little water in the form of urine. (True for camels)
- Statement B: Organism Q undergoes hibernation in extreme conditions. (True for polar bears)
- Statement C: Organism R has poison glands in the skin. (False for toucans; they do not have poison glands)

5. **Conclusion**: The statement that does not hold true for the organisms is the one about Organism R having poison glands in the skin.

### Final Answer:
The statement that does not hold true for organisms P, Q, and R is: "Organism R has poison glands in the skin."
