The correct answer is: Both A and R are true but R is not a correct explanation of A.
Nizam-ul-Mulk was a powerful and capable Wazir (Prime Minister) of the Mughal Empire. He was responsible for the administration of the empire and was a trusted advisor to the Mughal Emperor Muhammad Shah. However, Nizam-ul-Mulk became increasingly frustrated with Muhammad Shah’s incompetence and lack of leadership. He also felt that Muhammad Shah was not giving him the respect and authority that he deserved. In 1724, Nizam-ul-Mulk left the Mughal Empire and founded the State of Hyderabad.
There are several reasons why Nizam-ul-Mulk left the Mughal Empire. First, he was frustrated with Muhammad Shah’s incompetence and lack of leadership. Muhammad Shah was a weak and indecisive ruler who was easily manipulated by his courtiers. He was also addicted to opium and alcohol, which further impaired his ability to rule. Second, Nizam-ul-Mulk felt that Muhammad Shah was not giving him the respect and authority that he deserved. Nizam-ul-Mulk was a powerful and capable Wazir, and he felt that he should have been given more say in the affairs of the empire. Finally, Nizam-ul-Mulk was also concerned about the growing power of the Maratha Empire. The Marathas were a powerful Hindu warrior group that was expanding their territory at the expense of the Mughal Empire. Nizam-ul-Mulk believed that the Mughal Empire was in decline and that it was time for him to establish his own kingdom.
The reason given in the question for Nizam-ul-Mulk’s departure is that Muhammad Shah, instead of supporting his able Wazir, intrigued against him. This is true, but it is not the only reason why Nizam-ul-Mulk left the Mughal Empire. As discussed above, Nizam-ul-Mulk was also frustrated with Muhammad Shah’s incompetence and lack of leadership, and he was concerned about the growing power of the Maratha Empire.
In conclusion, both A and R are true, but R is not a correct explanation of A.
