Match the column : ( array |l|l|l|l| & Column I & & Column II & (Composition) & & (Alloy) (a) & Cu + Ni & (p) & Silver UK coins (b) & Ni + Cu + Zn & (q) & German silver (c) & Cu + Zn + Sn & (r) & Gun metal (d) & Ln (95 %)+ Fe & (s) & Misch metal array )

Options

  1. Aa-p, b-q, c-r, d-s
  2. Ba-q, b-r, s-s, d-p
  3. Ca-s, b-q, c-r, d-p
  4. Da-q, b-p, c-s, d-r

Correct answer

A. a-p, b-q, c-r, d-s

Step-by-step solution

Here's the correct pairing of the alloys and their compositions: - (a) ( Cu + Ni ) : (p) Silver UK coins - (b) ( Ni + Cu + Zn ) : (q) German silver - (c) ( Cu + Zn + Sn ) : (r) Gun metal - (d) ( Ln (95 %)+ Fe ) : (s) Misch metal Note: "Silver UK coins" are actually a copper-nickel alloy, not pure silver.
