The correct options are
A cross fostering
B filial imprinting
C sexual imprinting
The binding or attachment between the parents and the offspring is called filial imprinting. At times, we find the young one of a species raised by a parent of another species (e.g the chick of a cuckoo bird is fed by a crow in its nest). This behavioural pattern is called cross-fostering. Sexual imprinting is a process in which an individual animal learns to direct its sexual behaviour at a member of its own species.
