Explanations:The question revolves around the historical governance of Bengal under different rulers, specifically focusing on the Mughal and British periods. To understand the context, it is essential to delve into the historical background of Bengal's administration during these times.
Firstly, Iltutmish, who was a Mughal ruler, successfully asserted his authority over Bengal. He did not fail to crush the power of the governor of Bengal. Iltutmish was known for his strong centralization policies and his efforts to consolidate power, which included subduing regional governors who might have challenged his authority. Therefore, the first statement is false.
The second statement is true. The British were indeed forced to reunite Bengal in 1911. This decision was made in response to the growing nationalist movement in India, particularly in Bengal, which had been partitioned in 1905 to divide and rule the region. The partition had led to widespread protests and unrest, and the British government, under pressure, decided to reunite Bengal to quell the nationalist sentiments and centralize administration.
The third statement is also true. The British sought to maintain control over Bengal by installing a puppet ruler. This was a common strategy used by colonial powers to ensure that they could exert influence and control over the region without direct administration. By placing a ruler who was loyal to British interests, they could maintain a semblance of local governance while ensuring that their policies and decisions were implemented.
Thus, the correct answer is option D, which includes the second and third statements as true. The first statement is false, and therefore, options A, B, and C, which include the first statement, are incorrect.
