Explanation:

- Aurangzeb was a Mughal emperor who ruled from 1658 to 1707. He is known for his conservative and orthodox policies.

- In 1679, he reimposed the Jizya tax on non-Muslims, which had been abolished by his predecessors in the Mughal Empire.

- The Jizya tax was a per capita tax historically levied on non-Muslims. Its reinstatement was a part of Aurangzeb's efforts to enforce Islamic law.

- 1680 is the year after the tax was reimposed and does not relate directly to the Jizya's reinstatement.

- 1657 is before Aurangzeb came to power.

- 1705 is late in his reign but unrelated to the reimposition of the tax.

Option 3: 1679 is correct.
