Match List I with List II and select the correct answer using the code given below the Lists: List I (Phenomenon) A. Summer solstice B. Winter solstice C. Vernal Equinox D. Autumnal Equinox List II (Date) 1. 21st June 2. 22nd December 3. 23rd September 4. 21st March Code: A B C D

The Earth's axial tilt and its orbit around the Sun result in specific seasonal phenomena. In the Northern Hemisphere, the Summer Solstice occurs around 21st June when the Sun is directly over the Tropic of Cancer, marking the longest day [5]. The Winter Solstice occurs around 22nd December when the Sun is over the Tropic of Capricorn, resulting in the shortest day [2]. Equinoxes occur when the Sun is directly above the equator, leading to equal day and night globally [4]. The Vernal (Spring) Equinox in the Northern Hemisphere typically falls on 21st March, while the Autumnal Equinox occurs on 23rd September [4]. Matching these dates: A-1 (Summer Solstice - 21st June), B-2 (Winter Solstice - 22nd December), C-4 (Vernal Equinox - 21st March), and D-3 (Autumnal Equinox - 23rd September).
