Identify the correctly matched pair.

Options

A. Montreal protocol-Ozone depletion
B. Kyoto protocol-Ozone depletion
C. Ramsar convention - Ground water pollution
D. Basal convention - Biodiversity conservation

Answer

To solve the question of identifying the correctly matched pair, we will analyze each option provided:

1. **Montreal Protocol, ozone depletion**:
- The Montreal Protocol was established in 1987 to address the depletion of the ozone layer by phasing out the production and consumption of ozone-depleting substances. This is a well-known fact, making this pair a likely candidate for being correctly matched.

2. **Kyoto Protocol, ozone depletion**:
- The Kyoto Protocol, adopted in 1997, is primarily focused on combating climate change by reducing greenhouse gas emissions. It does not specifically address ozone depletion, making this pair incorrect.

3. **Ramsar Convention, groundwater pollution**:
- The Ramsar Convention is an international treaty that focuses on the conservation and sustainable use of wetlands. It does not specifically target groundwater pollution, so this pair is also incorrect.

4. **Basel Convention, biodiversity conservation**:
- The Basel Convention is aimed at controlling the transboundary movements of hazardous wastes and their disposal. It does not focus on biodiversity conservation, making this pair incorrect as well.

After analyzing all the options, we find that the only correctly matched pair is:

**Correct Answer: Montreal Protocol, ozone depletion.**
