• A. Daly
• B. John Quick
• C. Archibald Henderson
• D. Smedley Butler

Answer: (C)

Archibald Henderson earned the title Grand Old Man of the Marine Corps through his exceptionally long and influential leadership as the fifth Commandant, from 1820 to 1859. His nearly four-decade tenure solidified the Corps into a more professional, disciplined, and capable fighting force. He prioritized rigorous drill and training, standardized the organization and procedures, and built enduring traditions that strengthened Marine readiness for both shipboard and land operations. His sustained effort to grow the force and improve its governance left a lasting imprint on the Marine Corps, earning him the enduring nickname that highlights his pivotal role in shaping the service. The other figures are notable Marines but did not shape the Corps in the same historic, long-serving way as Henderson.
