Final answer:
The Navy and Marine Corps Medal is awarded for extraordinary heroism not justifying the Medal of Honor while serving with the Navy or Marine Corps.
Step-by-step explanation:
The medal awarded to individuals who, while serving in any capacity with the Navy or Marine Corps, distinguish themselves by extraordinary heroism, but do not qualify for the Medal of Honor, is the Navy and Marine Corps Medal (Option A).
This award recognizes acts of non-combat valor that still demonstrate exceptional courage or life-saving actions.
While there are various medals that acknowledge service and heroism, such as the Distinguished Service Medal, Silver Star Medal, and Bronze Star Medal, these are typically bestowed for different acts of military service or valor than the Navy and Marine Corps Medal.
