Explanation
World Environment Day is celebrated on 5th June. This answer is correct because the United Nations General Assembly designated June 5 as World Environment Day in 1972 to raise global awareness about environmental issues. The QuizMaster of AnsweringExams.Com suggests remembering this date by associating it with the number of fingers on a typical human hand, which is also five, making it easier to recall that World Environment Day falls on the 5th of June. Other options are incorrect because they do not align with the designated date by the United Nations, and celebrating on a different day would not serve the purpose of global unity in addressing environmental concerns.
