The correct answer is: B. June 5

World Ozone Day is celebrated on June 5 every year. It is a day to raise awareness about the importance of the ozone layer and the dangers of ozone depletion. The ozone layer is a region of Earth’s stratosphere that absorbs most of the Sun’s ultraviolet radiation. Ozone depletion is a gradual thinning of this layer caused by human activities.

The Montreal Protocol is an international treaty that was signed in 1987 to protect the ozone layer. The treaty has been successful in reducing the levels of ozone-depleting substances in the atmosphere. However, ozone depletion is still a problem, and it is important to continue to take steps to protect the ozone layer.
