Explanations:The question pertains to the geographical features off the coast of Mumbai, specifically the offshore oil fields. The Bombay High and Mumbai High are significant oil fields located in the Arabian Sea, approximately 150 kilometers off the coast of Mumbai, Maharashtra. These oil fields are crucial for India's energy sector and are often referred to interchangeably.
The term "Bombay High" is a historical name that dates back to the time when the city was known as Bombay. After the city's name was changed to Mumbai, the term "Mumbai High" began to be used as well. Both terms are correct and refer to the same geographical location. The oil fields were discovered in the 1970s and have been a significant source of crude oil for India ever since.
It is important to understand that the terms "Bombay High" and "Mumbai High" are not separate entities but refer to the same offshore oil fields. The use of both terms reflects the historical and contemporary naming conventions of the region. Therefore, the correct answer is "Both b) and c)" as both terms are valid and refer to the same geographical feature.
When studying geographical features, it is crucial to be aware of historical and contemporary naming conventions, especially in regions where names have changed over time. This knowledge is essential for competitive examinations where such details are often tested.
