Explanations:The province of Bengal, historically, was a significant region in the eastern part of the Indian subcontinent. It was a vast territory that included parts of present-day Bangladesh and the Indian state of West Bengal. The area of the province of Bengal was approximately 189,000 square miles, which is the correct answer to this question.
To understand the historical context, it is important to note that the province of Bengal was a major administrative division during the British colonial period in India. The region was known for its rich cultural heritage, diverse geography, and significant economic importance. The area of 189,000 square miles encompasses a wide range of landscapes, including the fertile Ganges-Brahmaputra delta, the Sundarbans mangrove forest, and the Himalayan foothills.
The historical province of Bengal was much larger than the current state of West Bengal, which is only a part of the former province. The current state of West Bengal, which is a part of India, covers an area of about 34,267 square miles, which is significantly smaller than the historical province. This difference in size is a common source of confusion for students and can lead to incorrect estimations of the area.
It is also important to note that the area of 189,000 square miles is a reasonable estimate for a large province in the Indian subcontinent. The other options provided in the question (18,900, 1,870,000, and 1,890,000 square miles) are either too small or too large to be accurate representations of the historical province of Bengal. The option of 18,900 square miles is too small, while the options of 1,870,000 and 1,890,000 square miles are too large, making them incorrect choices.
Understanding the historical context and the geographical extent of the province of Bengal is crucial for answering questions related to its area. This knowledge is often tested in competitive examinations such as the UPSC, SSC, Bank PO, and State PSC, where candidates are expected to have a good grasp of historical geography and the administrative divisions of the Indian subcontinent.
