The yz-plane is the plane that contains the y-axis and the z-axis. The point closest to the yz-plane is the point with the smallest x-coordinate. The x-coordinate of point A is 4, the x-coordinate of point B is 3, and the x-coordinate of point C is -2. Therefore, point C is closest to the yz-plane.

The Points a = (4, 1, 2), B = (3
