Question

Match List-I with List-II 

List-I	List-II
(A) Brass	(III) Zinc, Copper
(B) Bronze	(I) Tin, Copper
(C) Rubber molds	(IV) Latex
(D) Welding	(II) Silver

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

Hint:

Memorize the basic alloys: Brass = Copper + Zinc. Bronze = Copper + Tin. Then match the remaining specialized terms.

Answer 1

The Correct Option is A

Step 1: Match each item in List-I with its components or related material in List-II.

(A) Brass is an alloy primarily made of (III) Zinc, Copper.
(B) Bronze is an alloy primarily made of (I) Tin, Copper.
(C) Rubber molds, especially flexible ones, are commonly made from (IV) Latex.
(D) Welding is a process of joining metals. While it uses various materials, a common high-end application is brazing or soldering, which can use (II) Silver alloys. This is the most logical remaining connection.

Step 2: Compile the correct sequence of matches. The correct sequence is (A)-(III), (B)-(I), (C)-(IV), (D)-(II). This matches option (1).
