Show answer and explanation

Correct answer: (A) P–II; Q–IV; R–I; S–III

Explanation

Granite commonly metamorphoses into gneiss; limestone recrystallises into marble; quartz-rich sandstone becomes quartzite. A mafic parent such as gabbro can produce a schistose metamorphic rock under suitable conditions. The intended matches are P–II, Q–IV, R–I, S–III, A; actual metamorphic assemblages depend on grade and conditions.
