Considering India's global leadership in environmental protection and climate change sectors, which organisation had chosen India as the global host for World Environment Day (WED) on 5th June, 2018?

Correct option is C

The correct answer is (C) United Nations Environment Programme.

Explanation:
The United Nations Environment Programme (UNEP) is responsible for organizing World Environment Day (WED), which is observed annually on June 5. In 2018, India was selected as the global host to recognize its leadership in environmental conservation and climate action.

Information Booster:

• World Environment Day promotes global awareness and action on environmental issues.
• The theme for 2018 was "Beat Plastic Pollution."
• UNEP leads global environmental efforts, addressing climate change, pollution, and biodiversity conservation.

Additional Information:

• International Union for Conservation of Nature (IUCN) – Focuses on biodiversity conservation, not WED.

• European Environment Agency (EEA) – Monitors Europe’s environment, but does not host WED.
