Assertion : For the extraction of iron, haematite ore is used

Reason : Haematite is a carbonate ore of iron

(A)Only the reason is correct.
(B)Both the assertion and reason are correct and the reason is the correct explanation for the assertion.
(C)Only the assertion is correct✓ Correct
(D)Both the assertion and reason are correct, but the reason is not the correct explanation for the assertion

Answer: (C)

Solution

Haematite,

Fe X_{2} O X_{3}

, really is the ore used to extract iron, so the assertion is true. The reason, however, is wrong: haematite is an oxide of iron, not a carbonate, the carbonate ore of iron being siderite,

FeCO X_{3}

. So the assertion stands on its own while the reason does not.
