Correct answer: D

To match the conversions with conditions, use the standard hydrolysis conditions of nitrogen-containing derivatives.

1. Key facts

Nitrile hydrolysis requires very strong conditions: $\text{R-CN} \xrightarrow[300\,atm]{\text{NaOH},\ 623\,K} \text{RCOO}^- \xrightarrow{\text{H}_3\text{O}^+} \text{RCOOH}$ So nitrile $\to$ acid corresponds to (IV).
Amide hydrolysis under basic conditions occurs on heating, but milder than nitriles: $\text{RCONH}_2 \xrightarrow{\text{NaOH},\ 443\,K} \text{RCOO}^- \xrightarrow{\text{H}_3\text{O}^+} \text{RCOOH}$ So amide $\to$ acid corresponds to (III).
Acid chloride hydrolysis is very easy and occurs even with warm water: $\text{RCOCl} + \text{H}_2\text{O} \rightarrow \text{RCOOH} + \text{HCl}$ So acid chloride $\to$ acid corresponds to (I).
Ester hydrolysis (saponification followed by acidification) needs aqueous alkali but milder than amide hydrolysis: $\text{RCOOR'} \xrightarrow{\text{NaOH},\ 368\,K} \text{RCOO}^- \xrightarrow{\text{H}_3\text{O}^+} \text{RCOOH}$ So ester $\to$ acid corresponds to (II).

2. Matching

Thus the conversions must match as:

$A \to (IV)$
$B \to (III)$
$C \to (II)$
$D \to (I)$

3. Compare with options

This corresponds to Option D.

4. Verification with stored answer

Stored correct answer = D.

So my derived answer agrees with the stored answer.
