B. Edward H. Angle

C. Calvin Case 

D. Lawrence Andrews

The correct answer is B. Edward H. Angle.

Edward H. Angle, often considered the father of modern orthodontics, was known for his strong opposition to the extraction of teeth for orthodontic treatment. He believed in the concept of "normal occlusion" and advocated non-extraction treatment approaches. Angle believed that proper alignment and positioning of the teeth could be achieved without tooth extraction, even in cases of crowding or irregularity.
