Answer:
The correct answer will be option-B.
Step-by-step explanation:
Claude Bernard was a French physiologist who is known for his concept of homeostasis.
He made many discoveries in the field of medicine and provided a new concept called Milieu intérieur which was associated with the stability of the internal environment of the organisms which was later termed "Homeostasis" by Walter Bradford Cannon.
He explained the importance of the "internal environment" of the organism and showed that the living organism does not totally rely on the external environment.
Thus, option- B is the correct answer.
