Lattice Energy is directly proportional to charge on cation/anion and inversely proportional to center-to-center distance of cation and anion atoms…
(P.S. charge on cation/anion is a much more dominant factor)
Now, charge on BaO and CaO is 2 and size of Ba > size of Ca.
(charge on RbCl is 1 only)
Hence, lattice energy order CaO > BaO > RbCl
