The correct answer is: b) Cement production.
Meghalaya’s limestone deposits are particularly suitable for cement production because they are high in calcium carbonate. Calcium carbonate is the main ingredient in cement, and the higher the concentration of calcium carbonate in the limestone, the better the quality of the cement.
The other options are incorrect because they do not require limestone with a high concentration of calcium carbonate. Construction materials such as concrete and bricks can be made from a variety of materials, including limestone, but the quality of the materials is not as important as it is for cement production. Steel manufacturing does not require limestone at all, and fertilizer production can be done using a variety of materials, including limestone, but the quality of the limestone is not as important as it is for cement production.
In conclusion, Meghalaya’s limestone deposits are particularly suitable for cement production because they are high in calcium carbonate.
