Verified By Collegedunia
The Correct Option is D
Solution and Explanation
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:
\[
P\text{-}II,\quad Q\text{-}IV,\quad R\text{-}I,\quad S\text{-}III.
\]
