Question

Which pair correctly matches rock type and origin?

• A. Marble -- Igneous
• B. Granite -- Extrusive
• C. Sandstone -- Clastic sedimentary
• D. Basalt -- Intrusive

Hint:

Remember:
• Granite $\rightarrow$ Intrusive igneous
• Basalt $\rightarrow$ Extrusive igneous
• Marble $\rightarrow$ Metamorphic
• Sandstone $\rightarrow$ Clastic sedimentary

Answer 1

The Correct Option is C

Concept: Rocks are classified according to their mode of formation.

Step 1: Examine each option.
• Marble is a metamorphic rock, not igneous.
• Granite is an intrusive igneous rock, not extrusive.
• Sandstone is a clastic sedimentary rock formed by cementation of sand-sized particles.
• Basalt is an extrusive igneous rock, not intrusive.

Step 2: Identify the correct match. Hence, \[ \boxed{\text{Sandstone} \rightarrow \text{Clastic sedimentary rock}.} \] Therefore, the correct option is \[ \boxed{(C).} \]
