Option (A) is the correct answer.

Explanation:

It is known that like dissolves like. So, water being a polar solvent is able to dissolve ionic compounds in it.

For example, $CaCl_{2}$ is an ionic compound as it's atoms contain a metal and a non-metal.

Therefore, the bond present present in it is an ionic bond. Hence, when it is dissolved in water then its reaction equation is as follows.

$CaCl_{2}(s) \rightarrow Ca^{2+}(aq) + 2Cl^{-}(aq)$

Thus, we can conclude that $CaCl_{2}$ is soluble.

68% by mass = 68 / 100 => 0.68

Density = 1.504 g/mL⁻¹

Molar mass HNO₃ =63.01 g/mol

M = 1000 * T* D / mm

M = 1000 * 0.68 * 1.504 / 63.01

M = 1022.72 / 63.01

M = 16.23 mol/L

hope this helps!
