(b) Solubility of their sulphates in water
(c) Ionization energy
(d) Electronegativity

Answer 1

Answer:

Heyaa✌️✌️

Your right option is a)

The solubility of hydroxide of alkaline earth metals increases down the group due to the decrease in lattice energy and the hydration energy remains fairly constant.

Hope it helped you.
