Solution

The correct option is C Assertion is correct but Reason is incorrect
One cation vacancy is produced by one ${S r}^{2 +}$ because the charge neutralization is maintained. Hence, when $1 m o l$ of $N a C l$ is doped with $10^{- 3} m o l S r {C l}_{2}$ ; the cationic sites remaining vacant is $10^{- 3}$ .
