The correct answer is (d). Wetlands Day is observed on 2nd March every year. It is a day to raise awareness about the importance of wetlands and the need to protect them. Wetlands are areas of land that are saturated with water, either permanently or seasonally. They include swamps, marshes, bogs, and fens. Wetlands play an important role in the environment by filtering water, providing habitat for wildlife, and storing carbon. They are also important for recreation and education. However, wetlands are being destroyed at an alarming rate due to development, agriculture, and pollution. Wetlands Day is an opportunity to learn more about these important ecosystems and to take action to protect them.

(b) 2nd April is not Wetlands Day. It is Earth Day.
(c) 2nd May is not Wetlands Day. It is International Labour Day.
