Coterminal angles are angles in standard position. Recall, a complete cycle is 360 degrees or 2pi

To find a positive and a negative angle coterminal with a given angle, we add or subtract 360 degrees or 2pi

The given angle is 9pi/6

Thus,

The negative angle is

9pi/6 - 2pi = - 3pi/6

The positive angle is

9pi/6 + 2pi = 21pi/6

Thus, the correct option is the third one
