ANSWER:

D. √3/2

Explanation:

We have the following expression:


\tan\theta=-√(3)

Determine the angle to then evaluate in sine just like this:


\begin{gathered} \theta=\tan^(-1)(-√(3)) \\ \\ \theta=120\degree \\ \\ \text{ Therefore:} \\ \\ \sin120\degree=(√(3))/(2) \end{gathered}

Therefore, the correct answer is option D. √3/2
