Answer: D. 3\sqrt{2}

Step-by-step explanation:

The given fraction : \dfrac{6}{\sqrt{2}}

Here, the denominator is in radical form which makes it not an simplified form.

So , we rationalize it by multiplying \sqrt{2} to the numerator and the denominator , we get

\dfrac{6}{\sqrt{2}}\times\dfrac{\sqrt{2}}{\sqrt{2}=\dfrac{6\sqrt{2}}{2}}\\\\=\dfrac{2\times3\times\sqrt{2}}{2}\\\\=3\sqrt{2}  [Cancel 2 from the numerator and the denominator.]

Hence, the choice is equivalent to the given fraction = 3\sqrt{2}

Hence, the correct option is D. 3\sqrt{2}
