The correct option is (b) adaptation.
Explanation:
It takes some time for rhodopsin to split into scotopsin and retinal (bleaching) and release of transmitter passing nerve impulse via bipolar and ganglion cells to the optic nerves. This is a case of adaptation. It differs from accommodation which is a reflex mechanism by which the focus of the eye change to make the images of distant and near objects sharp on the retina.
