The correct answer is letter A
Instinct, or innate behavior, is an action that is impulsive or immediate based on a particular trigger or circumstance. Learned behavior is an action that someone learns or develops over time through observation, education, training or experience. Many scientists believe that most human behavior is the result of some level of both: instinctive behavior and learned behavior.
The crying, sucking and screaming of babies for food are examples of innate behaviors. Newborns often come out of the womb crying; therefore, this response to hunger, fear or discomfort is predetermined. Basic bodily actions, such as chewing, swallowing or reacting to physical pain are instinctive as well. Closing your eyes are innate defensive behaviors in response to someone throwing a ball at you. However, professional boxers and martial artists improve their responsiveness by forming faster reactions to these physical threats.
