The correct answer is: b) Limestone
Limestone is the most abundant mineral resource found in Mizoram. It is used in the manufacture of cement, lime, and other building materials. It is also used in the production of fertilizer and other chemicals.
Coal is a fossil fuel that is formed from the remains of plants and animals that lived millions of years ago. It is used to generate electricity and to produce steel.
Iron ore is a mineral that is used to make iron and steel. It is found in rocks and minerals that are rich in iron.
Petroleum is a fossil fuel that is formed from the remains of ancient plants and animals. It is used to make gasoline, diesel fuel, and other products.
Limestone is the most abundant mineral resource found in Mizoram because it is found in large deposits throughout the state. It is also relatively easy to mine and process. Coal, iron ore, and petroleum are also found in Mizoram, but they are not as abundant as limestone.
