• C. (a)-(iv), (b)-(i), (c)-(ii), (d)-(iii)
• D. (a)-(i), (b)-(iii), (c)-(iv), (d)-(ii)

Answer 1

The correct option is B (a)-(iv), (b)-(iii), (c)-(i), (d)-(ii)

The given lists are compounds and their preparation methods.
Sodium carbonate is prepared by solvay method.
Sodium carbonate is prepared by passing carbon dioxide through ammonia that gives ammonium carbonate. Subsequently ammonium carbonate is converted to ammonium hydrogen carbonate that reacts with sodium chloride to precipitate out sodium hydrogen carbonate. Sodium hydrogen carbonate later forms sodium carbonate.

Titanium : Van arkel method is used to purify crude titanium metal by heating the titanium metal with iodine to about 500K to form volatile compounds.
  

Chlorine: Deacon's process
In this process chlorine is produced by oxidation of gaseous $HCl$ with $O_2$ in the presence of a $CuC{l}_2$ catalyst.

$HCl+O_2\stackrel{CuC{l}_2}{\to }{H}_{2}O+C{l}_2$

Sodium hydroxide: Caster-Kellner cell
Castner–Kellner process is a method of electrolysis on an aqueous alkali chloride solution (usually sodium chloride solution) to produce the corresponding alkali hydroxide
