The given hydrochloric acid is a strong acid and completely dissociates in aqueous solution to produce H+ ions. 
HCl → H+ + Cl-
The given magnesium hydroxide is a strong base and completely dissociates in aqueous solution to produce OH- ions. 
Mg(OH)2 → Mg2+ + 2OH-
When these two solutions are mixed, the H+ ions react with the OH- ions to form water, leaving behind Mg2+ and Cl-. 
H+ + OH- → H2O
Since there is an excess of OH- ions in the solution, it will be basic. Therefore, the answer is B, basic.
