Solution

The correct option is C Assertion is incorrect but Reason is correct
The balanced reaction is as follows:
$M n O_{2} + 4 H C l ⟶ M n C l_{2} + 2 H_{2} O + C l_{2}$
Here, one mole of $M n O_{2}$ reacts with 4 mole of $H C l$ .
And in each reaction, the number of equivalents of all reactants and products are same.
So, one equivalent of $M n O_{2}$ reacts with one equivalent of $H C l$ .
