For precipitate formation reaction

(A) The reaction involves the formation of $CdS$ (cadmium sulfide) as a solid precipitate from the complex salt $K_2[Cd(CN)_4]$ upon reaction with $H_2S$.Since $CdS$ is a highly insoluble salt,it precipitates out of the solution.Therefore,this is a precipitate formation reaction.

Assertion : Addition of silver ions to a mixture of aqueous sodium chloride and sodium bromide solution will first precipitate $AgBr$ rather than $AgCl$.
Reason : $K_{sp}$ of $AgCl < K_{sp}$ of $AgBr$.
