Answer: 4. (a)-(iv), (b)-(iii), (c)-(ii), (d)-(i)

(a) Pure nitrogen: obtained by heating sodium azide or barium azide, (iv).
(b) Haber process: ammonia, (iii).
(c) Contact process: sulphuric acid, (ii).
(d) Deacon's process: chlorine from HCl and \(\mathrm{O_2}\) over \(\mathrm{CuCl_2}\), (i).

So (a)-(iv), (b)-(iii), (c)-(ii), (d)-(i): option (4).
