The correct option is B Instinct
∙ Instinctual behaviour is a type of behaviour that need not be learned. Instincts are present by birth. It is an automatic, immediate response to a particular stimulus. Reflexes are examples of instincts.
∙ Humans have instincts as that of animals. But the human instincts can be controlled. The immediate response can be stopped to certain extent.
E.g., When teacher punishes a student, he/she can react back in a similar way but the student doesn't do so. The student controls the instinct to behave in a good mannered way.
