Explanation: To understand the context of the statements, we need to delve into the historical events and figures mentioned.
1. **Robert Clive and Bengal**: Robert Clive, also known as Clive of India, was a British soldier and statesman who played a significant role in establishing British rule in India. He was appointed Governor of Bengal in 1765, not 1764. Clive's appointment came after the Battle of Buxar in 1764, which solidified British control over Bengal. The East India Company was granted the Diwani rights (the right to collect revenue) in Bengal, Bihar, and Orissa following the Treaty of Allahabad in 1765, which led to Clive's appointment as Governor.
2. **Nadir Shah and Bengal**: Nadir Shah was the Shah of Iran from 1736 to 1747. He invaded India in 1739, not Bengal specifically. His invasion culminated in the sack of Delhi, where he looted the city and took away the Peacock Throne and the Koh-i-Noor diamond. Nadir Shah's invasion was a significant event in Indian history, but it did not directly involve Bengal.
3. **"Bangla Desh" by George Harrison**: "Bangla Desh" is a song written by George Harrison, a member of the Beatles, in 1971. The song was inspired by the Bangladesh Liberation War, which was a conflict between East Pakistan (now Bangladesh) and West Pakistan (now Pakistan). The war resulted in the creation of Bangladesh as an independent nation. Harrison wrote the song to raise awareness about the humanitarian crisis and to support the people of Bangladesh. The song was part of his Concert for Bangladesh, which was one of the first major benefit concerts in history.
In summary, the first two statements are incorrect due to historical inaccuracies. Robert Clive was appointed Governor of Bengal in 1765, and Nadir Shah did not invade Bengal. The third statement is correct, as George Harrison did write "Bangla Desh" to raise awareness about the struggle in Bangladesh. Therefore, the correct answer is (C) Only 3.
