Assertion (A): Pravasi Bharatiya Divas is indeed celebrated on 9th January every year. It honors the contributions of the overseas Indian community to the development of India.
Reason (R): The date of 9th January was chosen for this occasion because it marks the return of Mahatma Gandhi to India from South Africa in 1915. His return was a significant event in Indian history, symbolizing the beginning of the Indian freedom struggle under his leadership.
Since both the assertion and the reason are true, and the reason provides the correct explanation for the assertion, the correct answer is Option (1).
