|
List I Alloys |
List II Constituents |
| A. Brass | I. Copper + tin |
| B. German Silver | II. Copper + Zinc |
| C. Coinage alloy | III. Copper + Zinc + Nickel |
| D. Bronze | IV. Copper + Nickel |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → A(II), B(III), C(IV), D(I)
Copper forms several common alloys:
A. Brass — This matches II. Copper + Zinc.
B. German Silver — This matches III. Copper + Zinc + Nickel. It contains no silver; the nickel gives it a silvery colour.
C. Coinage alloy — This matches IV. Copper + Nickel (cupronickel).
D. Bronze — This matches I. Copper + tin.
Shortcut: The pair A-(II) appears only in Option (3).
