Each set of parametric equations below describes the path of a particle that moves along the circle $x^2+(y-1)^2=4$ in some manner. Match each set of parametric equations to the path that it describes.

A. Once around clockwise, starting at (2, 1).
B. Three times around counterclockwise, starting at (2, 1).
C. Halfway around counterclockwise, starting at (0, 3).

1. $x=2\cos(t),\;\;y=1-2\sin(t),\;\;0 \le t \le 2\pi$
2. $x=2\cos(t),\;\;y=1+2\sin(t),\;\;\pi/2 \le t \le 3\pi/2$
3. $x=2\cos(t),\;\;y=1+2\sin(t),\;\;0 \le t \le 6\pi$
