Solution

The correct option is A Statement -1 is true, statement-2 is true; statement-2 is a correct explanation for statement-1
Cu(I) ion oxidizes and reduces simultaneously in aqueous solution to give Cu(II) and Cu ions. Therefore Cu(I) complexes are generally unstable in aqueous media and tend to disproportionate. For instance, the disproportionation of non-complexed Cu(I) in water is characterized by an equilibrium constant as large as $K_{d i s p} = 10^{6}$ .
