Which of the following is correctly matched
(a) Carrot grass `to` Lantana
(b) Farmers friend `to` Fungi
(c) Amazon rain forest `to` Lungs of planet
(d) World summit `to` Johannesburg

Options

A. only c, d
B. b, c, d
C. only d
D. a, b, d

Answer

To determine which of the following pairs is correctly matched, we will analyze each option one by one:

1. **Carrot grass `to` Lantana**:
- Carrot grass is known scientifically as Parthenium hysterophorus and is an invasive alien species in India. Lantana is another invasive species but is not the same as carrot grass. Therefore, this pairing is incorrect.

2. **Farmers friend `to` Fungi**:
- The term "Farmer's friend" typically refers to earthworms, which improve soil quality and crop yield. Fungi do play a role in soil health, but they are not commonly referred to as "Farmer's friend." Thus, this pairing is also incorrect.

3. **Amazon rain forest `to` Lungs of planet**:
- The Amazon rainforest is often referred to as the "lungs of the planet" because it produces a significant amount of oxygen and is vital for the Earth's ecosystem. This pairing is correct.

4. **World summit `to` Johannesburg**:
- The World Summit on Sustainable Development was held in Johannesburg in 2002. Therefore, this pairing is also correct.

Based on the analysis, the correctly matched pairs are:
- **(c) Amazon rain forest `to` Lungs of planet**
- **(d) World summit `to` Johannesburg**

Thus, the correct answer is options (c) and (d).
