Physics question multiple choice? Help please? :)?

B. Chromatic aberration: In optics, chromatic aberration (CA, also called achromatism or chromatic distortion) is a type of distortion in which there is a failure of a lens to focus all colors to the same convergence point. It occurs because lenses have a different refractive index for different wavelengths of light (the dispersion of the lens). The refractive index decreases with increasing wavelength. http://en.wikipedia.org/wiki/Chromatic_aberration ___ NOT A. Virtual image formation: An virtual image is an image that is formed not by the intersection of two light beams, but it appears that these light beams intersect at some point. The optics of convex mirror doesnt allow the light beams to intersect at any position of object in relation to the mirror. Thus one can never get any real image using convex mirror.

A) virtual image formation. the bending causes the light rays to appear to converge at a more nearer point and a virtual image is formed because the rays appear to converge at that point but they are not actually converging at that point.
