Question

Match List-I with List-II.

Choose the correct answer from the options given below :

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

Hint:

Brass is Cu-Zn, bronze is Cu-Sn, and stainless steel is an alloy of Fe, Cr, Ni, and C.

Answer 1

The Correct Option is B

This question requires matching alloys with their constituent elements. Let's examine each pair in the lists provided.

Bronze: Bronze is an alloy primarily composed of copper (Cu) and tin (Sn). This matches with (IV).

1. Brass: Brass is an alloy of copper (Cu) and zinc (Zn). This corresponds to (III).
2. UK silver coin: These coins used to be made primarily of copper (Cu) and nickel (Ni). This matches with (I).
3. Stainless Steel: This is an alloy that commonly includes iron (Fe), chromium (Cr), nickel (Ni), and carbon (C). Hence, it corresponds to (II).

Therefore, the correct matching is:

• (A) Bronze - (IV) Cu, Sn
• (B) Brass - (III) Cu, Zn
• (C) UK silver coin - (I) Cu, Ni
• (D) Stainless Steel - (II) Fe, Cr, Ni, C

The correct answer is: (A)-(IV), (B)-(III), (C)-(I), (D)-(II).

Answer 2

(A) Bronze: Bronze is an alloy of copper (Cu) and tin (Sn).
- (B) Brass: Brass is an alloy of copper (Cu) and zinc (Zn).
- (C) UK silver coin: UK silver coins are generally made with copper (Cu) and nickel (Ni).
- (D) Stainless Steel: Stainless steel is an alloy of iron (Fe), chromium (Cr), nickel (Ni), and carbon (C). Thus, the correct matching is: (A)-(IV), (B)-(III), (C)-(I), (D)-(II).
