Which coordinate marks the maximum point of the sine function?

Explanation:
The maximum value of the sine function is 1, and this occurs when the angle has reached pi/2 in its cycle. At x = pi/2, sin x = 1, so the coordinate (pi/2, 1) marks the peak. This peak repeats every 2 pi, but among the given points, this one is the only with y = 1. The other points correspond to zero crossings or the minimum value (-1), not the maximum. So the coordinate that marks the maximum point is (pi/2, 1).
