Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
$C_{12} H_{22} O_{11} + H_{2} O - - \to H^{+} C_{6} H_{12} O_{6} + C_{6} H_{16} O_{6}$
This reaction is first order reaction as Rate= $[C_{12} H_{22} O_{11}]$
The change of concentration of $H_{2} O$ is negligible. so, its impact on rate of reaction is negligible.
