Question

Match the rock with its metamorphosed form

• A. P-II, Q-IV, R-I, S-III
• B. P-III, Q-I, R-IV, S-II
• C. P-IV, Q-III, R-I, S-II
• D. P-II, Q-III, R-IV, S-I

Hint:

Sedimentary rocks commonly metamorphose into foliated or recrystallized rocks depending on mineral content and pressure–temperature conditions.

Answer 1

The Correct Option is D

To match the given rocks with their metamorphic forms: P: Granite → Gneiss (II) Granite, when subjected to high-grade metamorphism, becomes Gneiss. Q: Limestone → Marble (IV) Limestone undergoes recrystallization to form Marble. R: Sandstone → Quartzite (I) Sandstone, rich in quartz, metamorphoses into Quartzite. S: Gabbro → Schist (III) Gabbro, under metamorphic conditions, forms Schist due to mineral alignment. Thus, the correct matching is: \[ P\text{-}II,\quad Q\text{-}IV,\quad R\text{-}I,\quad S\text{-}III. \] Final Answer: (A)
