Autumnal ' equinox occurs on September 2 3. 4. Winter solstice occurs on June 2 1. Select the correct answer using the code given below :

The correct answer is Option 2 (1 and 3 only). In the Northern Hemisphere, these astronomical events are defined by the Earth's axial tilt and its orbit around the Sun.

• Statement 1 is correct: The Vernal (Spring) Equinox occurs around March 21. During this time, the Sun is directly overhead at the equator, resulting in nearly equal day and night globally.
• Statement 3 is correct: The Autumnal Equinox occurs around September 23. Similar to the Vernal Equinox, the Sun crosses the celestial equator moving southward, marking the beginning of autumn in the Northern Hemisphere.
• Statement 2 is incorrect: The Summer Solstice in the Northern Hemisphere occurs on June 21, when the North Pole is tilted closest to the Sun.
• Statement 4 is incorrect: The Winter Solstice occurs on December 22, when the Northern Hemisphere experiences its shortest day.

Since statements 1 and 3 represent the correct seasonal transitions for the Northern Hemisphere, Option 2 is the right choice.
