Solution

The correct option is D $B a (O H)_{2}$
In alkaline earth metal hydroxides, $K_{s p}$ increases down the group. So, $B a {(O H)}_{2}$ is the most soluble in water.

Among the following hydroxides, highest solubility in water will be shown by:

The correct option is D Ba(OH)2In alkaline earth metal hydroxides, Ksp increases down the group. So, Ba(OH)2 is the most soluble in water.

The correct option is D $B a (O H)_{2}$
In alkaline earth metal hydroxides, $K_{s p}$ increases down the group. So, $B a {(O H)}_{2}$ is the most soluble in water.
