The movement of elements of the environment relative to the observer is called Optic flow.
Optical flow is defined as the obvious motion of man or woman pixels at the image aircraft. It frequently serves as a very good approximation of the real physical motion projected onto the photo aircraft.
Movement-generated optic waft, as soon as detected, allows event belief and therefore, the perception of constituent items. A Neural hobby in Early motion-imaginative and prescient Neurons Is Modulated by Behavioral nation. Flies use optic waft—retinal photo shifts that are as a result of the relative motion among their eyes and their visible surroundings—to stabilize their on foot and flight paths, stability and gaze.
Optical glide is a vector subject among two snap shots, showing how the pixels of an object in the first picture may be moved to shape the identical object in the 2nd picture . it's far a type of correspondence studying, because if the corresponding pixels of an item are regarded, the optical go with the flow subject can be calculated.

Explanation:
Formal learning is the learning process that happens to occurs in formal and organized surroundings  such as classroom,organizations,online courses etc.
Informal learning is the learning which is for life-long , beyond the limitations of learning and gained from practical events of life.This learning provides successful working in the work environment.
According to the given options , informal learning is not highly present in organized and structured form and sometimes people do'nt get hint about the learning at the present stage rather realize it later. Instructor is present in formal learning to determine the path for learning in orderly way.
Thus, both the choices are correct, which makes option (c)  as the correct option.
