The stability of K2O, K2O2 and KO2 is in order K2O

Question

The stability of K2O, K2O2 and KO2 is in order K2O < K2O2 < KO2. This increasing stability as the size of metal ion increases is due to stabilisation of (A) larger cation by smaller anions through lattice energy effects (B) larger cation by larger anions through lattice energy effects (C) smaller cations by smaller anions through melting point (D) smaller cations by larger anions through melting point

Increase in the size of the cations, the stability increases. This is due to the stabilization of the larger cation with larger anion due to lattice energy effects.

Q. The stability of K2​O, K2​O2​ and KO2​ is in order K2​O<K2​O2​<KO2​. This increasing stability as the size of metal ion increases is due to stabilisation of

larger cation by smaller anions through lattice energy effects

larger cation by larger anions through lattice energy effects

smaller cations by smaller anions through melting point

smaller cations by larger anions through melting point

Increase in the size of the cations, the stability increases. This is due to the stabilization of the larger cation with larger anion due to lattice energy effects.

Q. The stability of $K_{2} O$ , $K_{2} O_{2}$ and $K O_{2}$ is in order $K_{2} O < K_{2} O_{2} < K O_{2}$ . This increasing stability as the size of metal ion increases is due to stabilisation of
