Solution

The correct options are
A $C H_{3} O H$
B $C a (O H)_{2}$
C $M g C l_{2}$
D $C a C l_{2}$
All the four compounds have some solubility in water.
Methanol is a polar and shows hydrogen bonding . Hence, it is soluble in water.
Others contain electropositive metal and electronegative non metal which results in ionic character. hence, they are soluble in water.
