D. Python

Answer

To determine the largest poisonous Indian snake, we need to analyze the options provided:

1. **Blue Krait**:
- The blue krait is indeed a poisonous snake found in the Indian subcontinent. However, it is not the largest poisonous snake in India. Therefore, this option is incorrect.

2. **Cobra**:
- The cobra, specifically the Indian Cobra (Naja naja), is known to be highly poisonous. It is also recognized as one of the largest poisonous snakes in India. Thus, this option is correct.

3. **King Cobra**:
- The King Cobra is the world's longest venomous snake, but it is not native to India in the same way as the Indian Cobra. While it is indeed a large poisonous snake, it is not typically classified as the largest poisonous snake in the context of Indian snakes. Therefore, this option is not the best answer.

4. **Python**:
- Pythons are non-venomous constrictors. They can cause harm through their strength and bites, but they do not possess venom. Hence, this option is incorrect.

Based on this analysis, the largest poisonous Indian snake is the **Cobra**.

### Summary of Steps:
1. Identify the options provided.
2. Analyze each snake's characteristics regarding size and venom.
3. Eliminate incorrect options based on size and venom status.
4. Conclude that the Cobra is the largest poisonous Indian snake.
