Solution

The correct option is C Assertion is correct but Reason is incorrect
Second analytical group of cations consist of ions that form acid $-$ insoluble sulfietes. These include $B i^{+ 3}, C d^{+ 2}, C u^{2 +}, A s^{3 +}, A s^{5 +}, S b^{+ 3}, S b^{+ 5}, S n^{+ 2}, S n^{+ 4}$ and $H g^{+ 2}, P b^{+ 2}$ is also included.
Silver and tin are placed in 1st and second group respectively, not on the basis of solubility of their salts.
