(D) As we move down group $2$ from $Mg(OH)_2$ to $Ba(OH)_2$:$1$. The basic character increases because the metallic character and the ease of releasing $OH^-$ ions increase due to the increase in atomic size.$2$. The chemical stability (thermal stability) increases as the electropositive character of the metal increases,making the $M-O$ bond stronger relative to the $O-H$ bond.$3$. The solubility in water increases because the lattice energy decreases more rapidly than the hydration energy as the size of the cation increases.Therefore,all three properties increase down the group.

Identify the option in which the trends corresponding to hydroxides of group $2$ elements (from $Mg(OH)_2$ to $Ba(OH)_2$) are correctly shown:
