Solution
The correct option is B Wald George Wald got the Nobel prize for describing the visual cycle. He proposed that vitamin A is an important component in rhodopsin, a light-sensitive compound in the retina, and explained in a series of studies from the 1930s to the 1960s that how light causes rhodopsin to change form and be converted. This conversion gives rise to signals in a complicated network of nerve cells by which a number of reconnections and transformations occur before the signals eventually are transformed into visual impressions in the brain.
