1) Mg(OH)2→ Mg2+ + 2 OH–
2) MgOH → Mg2+ + OH2–
3) Mg(OH)3→ Mg3+ + 3 OH–
4) Mg(OH)2→ Mg2+ + H2O

Number 1 does. Magnesium is has a +2 charge because its from group 2 on the periodic table.
And also the equation is balanced.

Dissociation means the compound splits into its positive part and its negative part. That would make #1 the answer.
#2 Since the OH radical has a -1 charge and Magnesium has a +2 charge (its in the second column of the periodic chart, you know), you can't have only one of each because the compound would not be neutral. Therefore MgOH is not the correct formula.
#3 Same reason as #2 - Mg is not +3.
#4 Is not dissociation and its not balanced
