Solution

The correct option is A Statement 1 and statement 2 are true and statement 2 is a correct explanation of statement 1.
Leaching is a widely used extractive metallurgy technique which converts metals into soluble salts in aqueous media.
Ores of $A l, A g$ and $A u$ are dissolved in suitable solvents to render the metals into solution which are further treated for extraction of the metals. In leaching the metals are dissolved to remove insoluble impurities like $F e_{2} O_{3}, T i O_{2}$ etc. (and the impurities are not dissolved out).

Statement 1 and statement 2 are true and statement 2 is a correct explanation of statement 1.
