The correct option is D It contains the Summer Solstice on June 21.
The Sun sets its motion northward from the Tropic of Capricorn at 23.5 S to the Tropic of Cancer at 23.5 N on June 21. The movement north is called Utharayanam. Utharayanam is marked by the gradual increase in the length of the day in India. This is due to the Northern Hemisphere tilted towards the Sun. The Utharayanam also contains the Summer Solstice on June 21.
