Correct answer is (b) True

Easiest explanation: Pure water is not a good solvent of minerals in most cases, but when the water is carbonated, its solvent action for many common minerals is enhanced. Thus, limestone is not easily soluble in pure water but carbonated water dissolves the rock effectively.
