The correct answer is Option (2) → June 21

International Yoga Day is celebrated every year on 21 June. The United Nations General Assembly declared the day on 11 December 2014, after Prime Minister Narendra Modi proposed it in his address to the UN in September 2014, and it was first celebrated in 2015. The date was chosen because 21 June is the summer solstice, the longest day of the year in the Northern Hemisphere.
