Explanations:The question asks about the largest oil field in India, which is a significant piece of information for understanding the country's energy resources and production capabilities. The correct answer is Mumbai High, which is located in the Arabian Sea off the coast of Mumbai, Maharashtra. This oil field is a crucial part of India's oil industry, contributing approximately 65% of the country's total oil production.
Mumbai High was discovered in 1974 and has been a major source of oil for India since then. The field is operated by Oil and Natural Gas Corporation (ONGC), which is a state-owned enterprise responsible for the exploration and production of oil and natural gas in India. The discovery of Mumbai High was a turning point for India's energy sector, as it significantly reduced the country's dependence on imported oil.
It is important to note that while Mumbai High is the largest oil field in India, there are other significant oil fields in the country, such as Ankaleshwar and Kalol in Gujarat. However, these fields do not produce as much oil as Mumbai High. Ankaleshwar and Kalol are important for the oil industry in Gujarat, but they do not contribute as significantly to the national oil production as Mumbai High does.
Surma Valley, mentioned in one of the options, is not related to oil production. It is a geographical region located in northeastern India, primarily in the state of Assam and parts of Bangladesh. The Surma Valley is known for its agricultural and ecological significance, but it is not a site of oil production.
Understanding the location and significance of major oil fields like Mumbai High is crucial for students preparing for competitive examinations, as it provides insight into the country's energy resources and the role of different regions in the national economy. This knowledge is particularly relevant for exams such as the UPSC, SSC, Bank PO, and State PSC, where questions on geography, energy resources, and economic geography are common.
