• A

  (a)-(iv), (b)-(i), (c)-(ii), (d)-(iii)
• B

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

  (a)-(i), (b)-(iv), (c)-(iii), (d)-(ii)
• Correct answer
  D

  (a)-(ii), (b)-(iii), (c)-(iv), (d)-(i)

Solution

$\mathrm{a}$ This reaction is Gattermann- Koch reaction (ii) in which benzaldehye is formed. $\mathrm{b}$ This reaction is haloform reaction (iii) which is given by methyl ketones and produce haloform as one of the product. $\mathrm{c}$ This reaction is esterification (iv) reaction which involves the formation of ester by reaction of aldehyde and ketone.
$\mathrm{d}$ This reaction is HVZ reaction (i), which involves alpha halogenation of carboxylic acid.

Hence, the correct answer is option: 'D'.
