The correct answer for the state in India that is the leading producer of Sulphur is option 2, Maharashtra. Sulphur is an important chemical element used in various industries such as fertilizers, pharmaceuticals, and chemicals. Maharashtra is known for its rich reserves of Sulphur, particularly in regions such as Raigad, Thane, and Pune. These areas have several Sulphur mines that contribute to the state`s significant production. It is essential to note that while Maharashtra is the leading producer, other states in India also have Sulphur deposits, but their production levels are comparatively lower. Therefore, option 2 is the correct choice based on the information provided.
