On 21st June, the Sun

On June 21st, the Summer Solstice occurs as the Northern Hemisphere tilts most towards the Sun, causing the "Midnight Sun" phenomenon where the Sun remains above the horizon for 24 hours at the Arctic Circle. Option (D) is incorrect because the Sun shines vertically overhead at the Tropic of Cancer on this date, whereas it is overhead at the Tropic of Capricorn during the Winter Solstice in December. This question tests the core concept of Earth's axial tilt and its relationship to seasonal variations and solar positions.
