Solution

The correct option is A $I > I I > I I I > I V$
Chlorine atom withdraws electron density from carbonyl carbon. Alkyl groups and alokxy groups add electron density to carbonyl carbon.
The decreasing order of electrophilic character of carbonyl carbon is $a c i d c h l o r i d e > a l d e h y d e > k e t o n e > e s t e r$
Hence, the decreasing order of reactivity for the nucleophilic addition reaction is $a c i d c h l o r i d e > a l d e h y d e > k e t o n e > e s t e r$
The correct option is option A. $I > I I > I I I > I V$
