[tex]\qquad\qquad\huge\underline{{\sf Answer}}[/tex]
Let's solve it ~
[tex]\qquad \sf \dashrightarrow \: {x}^{2} = \dfrac{9}{4} [/tex]
[tex]\qquad \sf \dashrightarrow \:x = \sqrt{ \dfrac{9}{4} } [/tex]
[tex]\qquad \sf \dashrightarrow \:x = \dfrac{ \sqrt{9} }{ \sqrt{4} } [/tex]
[tex]\qquad \sf \dashrightarrow \:x = \dfrac{3}{2} [/tex]
So, the correct choice is A
