Q1: Two gas based fertiliser plants are located in

ANS:A - Maharashtra and Gujarat

Two gas-based fertilizer plants are located in Maharashtra and Gujarat. These two states, Maharashtra and Gujarat, are major centers for industrial activity in India and are also known for their access to natural gas reserves. As a result, gas-based fertilizer plants have been established in these regions to take advantage of the availability of natural gas as a feedstock for fertilizer production. Gas-based fertilizer plants use natural gas, which is a cleaner and more efficient feedstock compared to other sources such as coal or oil. The proximity to natural gas reserves or gas pipelines makes Maharashtra and Gujarat suitable locations for the establishment of these plants.
