The question asks for the simplified form of $\frac{2}{\sqrt{3}}$.

To simplify $\frac{2}{\sqrt{3}}$, follow these steps:

1. Rationalize the denominator: Multiply both the numerator and the denominator by $\sqrt{3}$ to eliminate the square root in the denominator. $\frac{2}{\sqrt{3}} \times \frac{\sqrt{3}}{\sqrt{3}} = \frac{2\sqrt{3}}{3}$

So, the simplified form of $\frac{2}{\sqrt{3}}$ is $\frac{2\sqrt{3}}{3}$.

The correct answer is E: $\frac{2}{3} \sqrt{3}$.
