B) 0
C) -1
D) undefined

Question

Quizplus · Accepted Answer

Since tangent is opposite over adjacent, and the opposite side to angle 0 is 0 (since it passes through the center of the circle), and the adjacent side is not present, the tangent of angle 0 is undefined. Therefore, the correct choice is B.
