Solution

The correct option is C Assertion is correct but Reason is incorrect
The addition of silver ions to a mixture of aqueous sodium chloride and sodium bromide solution, will first precipitate $A g B r$ rathar than $A g C l$ means $A g B r$ is less soluble than $A g C l$ so $K_{s p}$ of $A g B r$ < $K_{s p}$ of $A g C l$ .
