Solution

The correct option is C Assertion is incorrect but Reason is correct
$C H_{3} C O$ group in aldehydes and ketones gives iodoform test.

Although $C H_{3} C O C H_{2} C O O C_{2} H_{5}$ contains the $C H_{3} C O$ group required for iodoform test yet it does not give this test since here $H$ -atoms of $C H_{2}$ group being flanked by two electron withdrawing groups are more acidic than $H$ atoms of the $C H_{3}$ group. As a result, iodination preferentially occurs at $C H_{2}$ group and hence $C H I_{3}$ is not formed.

From the structure, we can easily say the reason is correct.

Hence correct option is $C$ .
