B
usually follows the reception of a sign stimulus
C
is a limited time in which imprinting can occur
D
is the period during which birds can learn to fly
Explanation: 

Detailed explanation-1: -Filial imprinting in precocial birds is the process of forming a social attachment during a sensitive or critical period, restricted to the first few days after hatching. Imprinting is considered to be part of early learning to aid the survival of juveniles by securing maternal care.

Detailed explanation-2: -Imprinting is used in psychology and ethology to describe any kind of learning that occurs at a particular age or stage of development. A phase-sensitive type of learning, it involves an organism recognizing the characteristics of certain stimuli that are subsequently “imprinted” onto the subject.

Detailed explanation-3: -Hess (1958) showed that although the imprinting process could occur as early as one hour after hatching, the strongest responses occurred between 12 and 17 hours after hatching, and that after 32 hours the response was unlikely to occur at all.

Detailed explanation-4: -The phrase ‘sensitive periods’ often conjures up thoughts of moody teenagers, but it actually refers to a period of time when a child’s interests are focused on developing a particular skill or knowledge area. According to Montessori Theory, the most important sensitive periods occur between birth and age six.
