A concave lens is used to form an image. The diagram shows three incident rays that pass the object and then reach the lens. How
does the lens affect the blue ray, which is incident on a path headed to the focal point on the right?
A. The ray bends outward on a path that traces back to the focal point on the left.
B. The ray bends so that it emerges from the lens travelling parallel to the axis.
C. The ray continues on its path and travels through the focal point on the right.
D. The ray bends outward on a path that traces back to the vertex of the lens.
