The correct answer is D) Nawab Saadat Khan.
Saadat Khan Burhan-ul-Mulk was appointed the Nizam (Governor) of Awadh by the Mughal Emperor Muhammad Shah in 1722. He gradually asserted his independence from the weakening central Mughal authority, laying the foundation for the autonomous state of Awadh in the 18th century. He is considered the founder and first Nawab Wazir of Awadh.
Saadat Khan was succeeded by his nephew Safdarjung, who became the second Nawab Wazir. Safdarjung was followed by Shuja-ud-Daula, the third Nawab Wazir. Saadat Ali Khan was a later ruler of Awadh, serving from 1798 to 1814.
