Dear student,
The answer of 18 is (a). The layer of the retina which faces the lens is the ganglion cell layer.This can be explained by an image shown below in which the light entering the lens is faced by ganglion cells followed by bipolar and photoreceptors cells of the retina.
.
The answer of 19 is (a). Twilight vision is the scotopic vision which occurs in the dim light that involves only the retinal rods as light receptors.
Regards
