The correct answer is option 4, Mauzzam. Mauzzam succeeded Aurangzeb as the Mughal emperor. He was also known as Muhammad Azam Shah. After the death of Aurangzeb in 1707, a power struggle ensued among his sons. Mauzzam emerged victorious and ascended the throne as the emperor. Azam, mentioned in option 1, is another name for Mauzzam, so option 1 is a correct alternative name for the same person. Option 2, Kam Baksh, and option 3, Akbar II, are incorrect as they were not the successors of Aurangzeb. It is important to note that while Mauzzam initially had control over the throne, his reign was short-lived and he was soon overthrown by his brother, Bahadur Shah I.
