Match List - I with List - II.

           List -I                       List - II
(A)   Bronze                        (I)  Cu, Ni
(B)   Brass                          (II) Fe, Cr, Ni, C
(C)   UK Silver coin            (III)  Cu, Zn
(D)   Stainless Steel         (IV)   Cu, Sn
 
Choose the correct answer from the options given below :

Bronze is an alloy of $$Cu$$ and $$Sn$$, therefore List-I item (A) corresponds to List-II entry (IV).

Brass is an alloy of $$Cu$$ and $$Zn$$, therefore List-I item (B) corresponds to List-II entry (III).

The present-day United Kingdom “silver” coin actually contains no silver; it is a cupronickel alloy of $$Cu$$ and $$Ni$$, so List-I item (C) matches List-II entry (I).

Stainless steel typically contains $$Fe, Cr, Ni$$ and a small amount of $$C$$, hence List-I item (D) matches List-II entry (II).

Thus the correct matching is:
(A) → (IV), (B) → (III), (C) → (I), (D) → (II).

Option B which is: (A)-(IV), (B)-(III), (C)-(I), (D)-(II)
