Name a submarine weapon and a capability.

• A. Mk 48 ADCAP - acoustic homing; can destroy submarines and ships
• B. Tomahawk cruise missile
• C. Harpoon anti-ship missile
• D. Torpedo tube launches only

Answer: (A)

The essential idea is recognizing a submarine’s primary offensive tool and its guiding capability. The Mk 48 ADCAP is a submarine-launched torpedo equipped with acoustic homing, which gives it the ability to locate and strike both submarines and surface ships by following sound signals. That combination—a potent torpedo carried by submarines and the acoustic-homing guidance—best matches a submarine weapon with a clear capability. The other options don’t fit as a submarine-specific weapon with a defined capability: Tomahawk is a land-attack cruise missile, Harpoon is an anti-ship missile not typically tied to submarine launch, and “torpedo tube launches only” describes a launch method rather than naming a weapon and its capability.
