A
Mg²⁺
B
Ca²⁺
C
Sr²⁺
D
Ba²⁺

Solution:

Number of shells increases size increases down the group in alkali metals.

cation size $\infty \frac{1}{polarizing power} \infty ionic charecter \infty melting point \infty \frac{1}{covalent character}$ , hence Ba²⁺ion has pairing with O^-2 has maximum melting point.
