$Option A$ $"Option A"$

Explanation:

We need a stoichiometric equation that represents the reaction between $M {g (O H)}_{2}$ $Mg(OH)_2$ and $H C l$ $HCl$ , and here it is............

$M {g (O H)}_{2} (s) + 2 H C l (a q) \to M g C l_{2} (a q) + 2 H_{2} O (l)$ $Mg(OH)_2(s) + 2HCl(aq) rarr MgCl_2(aq) + 2H_2O(l)$

Here, $1$ $1$ $equiv$ $"equiv"$ of magnesium hydroxide reacts with $2$ $2$ $equiv$ $"equiv"$ hydrochloric acid. In the reaction that was performed, there were $3.0 \cdot m o l$ $3.0*mol$ hydrochloric acid, and stoichiometric equivalence a $\frac{1}{2}$ $1/2$ $equiv$ $"equiv"$ of $magnesium hydroxide$ $"magnesium hydroxide"$ , i.e. $\frac{3}{2} \cdot m o l$ $3/2*mol$ .
