Answer

To solve the question "Which of the following forests is known as the 'lungs of the planet earth'?", we can follow these steps:

### Step 1: Understand the Question
The question is asking for a specific forest that is commonly referred to as the "lungs of the planet earth." This phrase typically refers to a forest that plays a significant role in oxygen production and carbon dioxide absorption.

### Step 2: Analyze the Options
We have four options to consider:
1. Taiga Forest
2. Tundra Forest
3. Amazon Rainforest
4. Rainforest of Northeast India

### Step 3: Evaluate Each Option
- **Taiga Forest**: This forest does produce oxygen but is not the largest contributor to global oxygen production.
- **Tundra Forest**: Similar to taiga, tundra does produce oxygen but is not known for significant oxygen production relative to other forests.
- **Amazon Rainforest**: This forest is known for its vast size and biodiversity. It produces about 20% of the world's oxygen, which is why it is often referred to as the "lungs of the planet."
- **Rainforest of Northeast India**: While this rainforest is important, it does not have the same level of global impact in terms of oxygen production as the Amazon.

### Step 4: Identify the Correct Answer
Based on the analysis, the Amazon Rainforest is the forest that is known as the "lungs of the planet earth" due to its significant contribution to oxygen production and its vast biodiversity.

### Final Answer
The correct answer is **Amazon Rainforest**.
