To vary the angle as well as the intensity of polarized light, ordinary unpolarized light is passed through one polarizer with its transmission axis vertical and then a second polarizer is placed between the first polarizer and the insect. When the light leaving the second polarizer has half the intensity of the original unpolarized light, which statement is true about the two types of cells?

1. A.    Only type H detects this light.
2. B.     Only type V detects this light.
3. C.     Both types detect this light, but type H detects more light.
4. D.    Both types detect this light, but type V detects more light.
