Bijapur was annexed by Aurangzeb in which year?

1685

The correct answer is Option 2- 1685

Aurangzeb invaded Bijapur in 1685 and laid siege to the city. The siege lasted for over a year, and Bijapur eventually surrendered in 1686. The Adil Shahi dynasty, which had ruled Bijapur for over 200 years, came to an end.

Therefore, as per the given options, 1685 is the most appropriate answer.

The annexation of Bijapur was a major victory for Aurangzeb and helped to expand the Mughal Empire to its greatest extent. However, it also led to increased resistance from the Marathas and other regional powers, which contributed to the decline of the Mughal Empire in the 18th century.
