Well, at a guess, I would plump for
Explanation:
Lattice energy depends on two parameters: (i) the size of the ion; and (ii) the charge on the ion...
Why? Well, to a first approx. the electrostatic interaction depends on old Coulomb's law...and inverse square law. And clearly, those ions that are smaller will have GREATER electrostatic interaction....because of the
And also since the electrostatic interaction CLEARLY also depends on the charge of the individual ions...we would choose the
