Answer:
The correct answer is: This behavior is likely to increase gosling survival
Explanatio
Animal behavior is dependent on physiological frameworks and procedures. It is a basic piece of securing nutrients for digestion and finding an accomplice for sexual multiplication. Behavior likewise adds to homeostasis,as in bumble bees crouching to preserve heat .To put it plainly, all of animal physiology adds to behavior,and animal behavior impacts the entirety of physiology.
Imprinting is done by graylag goslings after they hatch, when they hatch they quickly become bonded to the nearby moving object they encounter.In the natural environment, imprinting goes about as a nature for survival in young birds. The young bird should immediately recognize its parent immediately after hatching inorder to avoid getting attack by predators. Thus, imprinting is very reliable to induce the formation of a strong social bond between offspring and parent, even if it is the wrong one.

The neural plate is one of the features exclusive to the embryonic development of chordates. It is located dorsally to the notochord. The neural plate is the rudimentary nervous system of the embryo. During early development ,the neural plate is formed from the ectodermal layer . It undergoes changes in the position and arrangement of it's cells to form the brain and the spinal cord which comprises the central nervous system. It forms tissues and eventually organs by the deepening of the groove which forms ridges which eventually folds and fuses to form the neural tube . The tube differentiates into the prosencephalon, the mesencephalon and the rhombencephalon, from which the organs are formed
