Step-by-step explanation
To match the items from List I to List II, we need to understand the composition of each material:
Bronze is an alloy composed of copper (Cu) and tin (Sn).
Brass is an alloy made of copper (Cu) and zinc (Zn).
The UK silver coin primarily consists of copper (Cu) and nickel (Ni).
Stainless steel is an alloy that includes iron (Fe), chromium (Cr), nickel (Ni), and carbon (C).
Based on these definitions, the correct matches are:
(A) Bronze corresponds to (IV) Cu, Sn
(B) Brass corresponds to (III) Cu, Zn
(C) UK silver coin corresponds to (I) Cu, Ni
(D) Stainless steel corresponds to (II) Fe, Cr, Ni, C
These pairings illustrate the composition of each material and ensure accurate alignment between List I and List II.
