Question

Match List-I (Parent rock) with List-II (Metamorphic rock):

• (A) - (I), (B) - (II), (C) - (III), (D) - (IV)
• (A) - (III), (B) - (II), (C) - (I), (D) - (IV)
• (A) - (I), (B) - (III), (C) - (IV), (D) - (II)
• (A) - (III), (B) - (IV), (C) - (I), (D) - (II)

Hint:

Remember parent-to-metamorphic transitions: Slate → Phyllite, Coal → Graphite, Sandstone → Quartzite.

Answer 1

The Correct Option is B

Step 1: Conglomerate recrystallises to Gneiss under regional metamorphism.
Step 2: Slate progresses to Phyllite under increasing grade.
Step 3: Coal is reduced to Graphite, and Sandstone recrystallises to Quartzite.
Step 4: Matching each pair gives the correct option, (A)-(III), (B)-(II), (C)-(I), (D)-(IV).
