The correct answer is (a) Bahadur Shah I.
Aurangzeb was the sixth Mughal emperor who ruled over India from 1658 to 1707. He was a powerful and ruthless ruler who expanded the Mughal Empire to its greatest extent. However, his reign was also marked by religious persecution and economic decline.
Aurangzeb died in 1707 at the age of 88. He was succeeded by his son Bahadur Shah I, who ruled for five years. Bahadur Shah was a moderate ruler who tried to restore peace and prosperity to the Mughal Empire. However, he was unable to control the growing power of the Marathas, who eventually overthrew the Mughal Empire in 1757.
(b) Jahandar Shah was the second son of Aurangzeb who ruled for a brief period of two years from 1707 to 1709. He was a weak and incompetent ruler who was eventually overthrown by his brother Bahadur Shah I.
(c) Mohammad Shah was the fourth son of Aurangzeb who ruled for a period of 30 years from 1719 to 1748. He was a weak and pleasure-seeking ruler who was unable to control the growing power of the Marathas.
(d) Akbar II was the great-grandson of Aurangzeb who ruled for a brief period of two years from 1760 to 1762. He was a weak and indecisive ruler who was unable to stop the decline of the Mughal Empire.
