Assertion (A): Marble is a good building stone due to its compact crystalline structure. Reason (R): Marble is a metamorphic rock formed from limestone under heat and pressure.
Both A and R are true and R explains A
Both A and R are true but R does not explain A
A is true but R is false
A is false but R is true
Assertion (A): Acid test is mainly used to detect the presence of calcium carbonate in stones. Reason (R): Stones containing calcium carbonate react with hydrochloric acid causing surface deterioration.
Both A and R are true and R explains A
Both A and R are true but R does not explain A
A is true but R is false
A is false but R is true
