STATEMENT-1 : `NaCN` acts as a depresent for `ZnS` but does not prevent `PbS` from the formation of froth.
and
STATEMENT-2 : `NaCN` combines with `ZnS` to form a complex `Na_(2)[Zn(CN)_(4)]` on the surface of `ZnS` and thus prevents it from formation of froth.

B

Statement-1 is True, Statement-2 is True, Statement-2 is not a correct explanation for Statement-1

C

Statement-1 is True, Statement-2 is False
