Select and explain. 
A. Movement, depth and flicker, B. Color vision, shape and fine details, C. Temporal frequency, D. Luminance contrast
B: Color vision, shape and fine details
Answer: B: Color vision, shape and fine details 
Explanation: From the lateral geniculate nucleus, a magnocellular pathway and a parvocellular pathway project to the visual coex. The parvocellular pathway, from layers 3-6, carries signals for color vision, texture, shape, and fine detail. The parvocellular pathway also carries color opponent data to the deep pa of layer 4.Ref: Ganong's Review of Medical Physiology, Twenty-Third Edition
