Solution

The correct option is A $M g (O H)_{2} < C a (O H)_{2} < S r (O H)_{2} < B a (O H)_{2}$
The correct order of thermal stability of hydroxide is
$M g (O H)_{2} < C a (O H)_{2} < S r (O H)_{2} < B a (O H)_{2}$
On moving down the group, the lattice enthalpy increases and the thermal stability increases.
Hence, option $B$ is correct.
