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 asks 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 producing oxygen and absorbing carbon dioxide.

### Step 2: Analyze the Options
We have four options to consider:
1. Western Ghats
2. Lake Victoria
3. Green Glands
4. Amazon Rainforest

### Step 3: Evaluate Each Option
- **Western Ghats**: This is a mountain range in India, not a forest. While it has forests, it is not primarily known as a forest.
- **Lake Victoria**: This is a large lake in East Africa, not a forest. It does not contribute to the description of "lungs of the planet."
- **Green Glands**: These are excretory structures found in some arthropods, not related to forests at all.
- **Amazon Rainforest**: This is a vast tropical rainforest in South America, known for its biodiversity and significant role in oxygen production and carbon dioxide absorption.

### Step 4: Identify the Correct Answer
From the evaluation, the Amazon Rainforest is the only option that fits the description of being the "lungs of the planet earth" due to its extensive forest area and ecological importance.

### Conclusion
The correct answer is **Amazon Rainforest**.
