    None of these

    Explanation

    We know that, Area of an equilateral triangle is given by the formula area=  34×(side)2area = \;\frac{{\sqrt 3 }}{4} \times {\left( {side} \right)^2} ⇒43=34×(side)2\Rightarrow 4\sqrt 3 = \frac{{\sqrt 3 }}{4} \times {\left( {side} \right)^2} ⇒ side 2 = 4 cm × 4 cm ⇒ side = 4 cm
