C. Ammonotelic - - - - - Tadpole
D. Ureotelic - - - - - - - - Elephant

Answer

To solve the question of identifying the wrong pair regarding nitrogenous waste excretion, we can follow these steps:

### Step 1: Understand the Terms
- **Uricotelic**: Organisms that excrete uric acid as their nitrogenous waste.
- **Ureotelic**: Organisms that excrete urea as their nitrogenous waste.
- **Ammonotelic**: Organisms that excrete ammonia as their nitrogenous waste.

### Step 2: Analyze Each Option
1. **Uricotelic - Birds**:
- Birds excrete uric acid. This pair is correct.

2. **Ureotelic - Insects**:
- Insects primarily excrete uric acid, not urea. This pair is incorrect.

3. **Ammonotelic - Tadpole**:
- Tadpoles are aquatic and excrete ammonia. This pair is correct.

4. **Ureotelic - Elephants**:
- Elephants, being mammals, excrete urea. This pair is correct.

### Step 3: Identify the Wrong Pair
From the analysis, the only incorrect pair is:
- **Ureotelic - Insects** (Insects are uricotelic, not ureotelic).

### Conclusion
The wrong pair is **Ureotelic - Insects**.
