Explanations:The question involves assessing the historical accuracy of three statements related to British colonial rule in Bengal. Each statement pertains to a significant event or geographical fact that is crucial to understanding the historical context of British expansion in India.
The first statement asserts that Robert Clive introduced the system of dual government in Bengal. This is historically accurate. Robert Clive, a prominent figure in the British East India Company, implemented the dual government system in Bengal after the Battle of Plassey in 1757. Under this system, the Nawab of Bengal was nominally the ruler, but the British East India Company had significant control over the administration and revenue collection. This arrangement allowed the Company to exert considerable influence over the region without directly assuming the role of the ruler.
The second statement claims that the Battle of Plassey marked the beginning of the end of Nawab rule in Bengal. This is also true. The Battle of Plassey, fought on June 23, 1757, was a decisive victory for the British East India Company over the Nawab of Bengal, Siraj-ud-Daulah. This battle significantly weakened the Nawab's authority and paved the way for British dominance in the region. The subsequent dual government system further diminished the Nawab's power, leading to the eventual decline of Nawab rule in Bengal.
The third statement states that the mouth of the Ganges River is at the Bay of Bengal. This is a geographical fact and is correct. The Ganges River, one of the most significant rivers in India, flows through the northern part of the country and empties into the Bay of Bengal. The delta formed by the Ganges and its tributaries is a vast and fertile region, known for its agricultural productivity and ecological significance.
Each of these statements is independently true and collectively provides a comprehensive understanding of the historical and geographical context of British rule in Bengal. Therefore, the correct answer is that all three statements are true, which corresponds to Option C.
