Solution

The correct option is D Both Assertion and Reason are incorrect
One mole of thionyl chloride reacts with two moles of water to form two moles of HCl.
$2 H_{2} O + S O_{2} C l_{2} \to 2 H C l + H_{2} S O_{4}$
Two moles of $H C l$ are neutralized by two moles of $N a O H$ .
Thus, both assertion and reason are incorrect.
