The correct option is B A: Instinct
B: Conditioning
∙ 'A' is instinctual behaviour. Instinctual behaviours need not be learned and is present by birth. For example, a bird knows how to build nest and all the birds in the following generations can also build nest in the same way.
∙ 'B' is conditioning. Learning to do something with experience is called conditioning. For example, we are conditioned to reach out to our mobile phones when we hear our ringtone.
