Question

Match List-I with List-II 

List-I	List-II
(A) Plaster of Paris	(IV) Gypsum
(B) Non-ferrous metal	(III) Gold
(C) Cement	(I) Calcium aluminum silicate
(D) Alloy	(II) Bronze

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

Hint:

Break down material definitions: Plaster comes from Gypsum. Bronze is an Alloy. Gold is a non-ferrous element. Cement is a complex silicate.

Answer 1

The Correct Option is C

Step 1: Match each term in List-I with its correct example or chemical basis in List-II.

(A) Plaster of Paris is made from heating (IV) Gypsum (calcium sulfate dihydrate).
(D) An Alloy is a mixture of metals. (II) Bronze (copper and tin) is a classic example of an alloy.
(B) A Non-ferrous metal is one that does not contain iron. With Bronze identified as the alloy, (III) Gold is the best example of a non-ferrous elemental metal.
(C) Cement is a binder, and its primary chemical constituents are silicates and aluminates of calcium, i.e., (I) Calcium aluminum silicate.

Step 2: Assemble the correct pairings. The correct matches are (A)-(IV), (B)-(III), (C)-(I), (D)-(II). This matches option (3).
