Next, unpolarized light is reflected off a smooth horizontal piece of glass, and the reflected light shines on the insect. Which statement is true about the two types of cells?

(a) When the light is directly above the glass, only type V detects the reflected light.

(b) When the light is directly above the glass, only type H detects the reflected light.

(c) When the light is about 35° above the horizontal, type V responds much more strongly than type H does.

(d) When the light is about 35° above the horizontal, type H responds much more strongly than type V does.

Some insect eyes have two types of cells that are sensitive to the plane of polarization of light. In a simple model, one cell type (type H) is sensitive to horizontally polarized light only, and the other cell type (type V) is sensitive to vertically polarized light only. To study the responses of these cells, researchers fix the insect in a normal, upright position so that one eye is illuminated by a light source. Then several experiments are carried out.
