Answer:
Option A
Explanation:
As per the principle of intrinsic fitness, a person likes to work for his/her inner satisfaction driven by motivation within him/herself.
Thus, a young bird which feels an urge to produce chicks by mating each year will ultimately go outside to find his/her mate on their own and will produce chick every year. In an intrinsic behaviour the rewards achieved are internally self satisfying and thus a person need no assistance in achieving them on their own.
Thus, option A is correct.
