• A. Orthopedics
• B. Radiology
• C. Dermatology
• D. Surgery

Answer: (D)

Surgery is the field defined by diagnosing and treating conditions through physically altering tissues with operative procedures, which can range from minor interventions to major operations. This description captures the broad scope of surgical practice, including cutting, removing, repairing, or reconstructing tissue to address disease or injury. The other disciplines don’t fit this comprehensive definition: orthopedics is a surgical specialty focused specifically on the musculoskeletal system, rather than the whole body; radiology centers on imaging techniques to diagnose conditions and guide treatment rather than performing tissue-altering procedures; dermatology deals with skin diseases and usually uses non-surgical management, with only some minor procedures. So the branch described by the statement is surgery.
