Which major WWI weapon was used to break trench warfare stalemate?

• A. Dreadnought battleships
• B. Tanks
• C. Submarines
• D. Chemical weapons

Answer: (B)

Trench warfare produced a stalemate because fortified networks of trenches, barbed wire, and machine-gun fire made frontal assaults deadly and ground gains hard to achieve. Tanks were designed to change that dynamic by crossing trenches, rolling over craters, and breaking through wire while protecting advancing infantry from concentrated fire. Even though early tanks were slow and imperfect, their mobility started to shift battles toward a breakout, especially when used with artillery and infantry in a coordinated attack. This combination allowed Allied forces to punch through entrenched lines and begin shifting the front in 1918, helping to end the stalemate. Dreadnought battleships operate at sea, submarines primarily disrupt supply lines rather than breach land defenses, and chemical weapons caused casualties and fear but did not deliver lasting breakthroughs, making tanks the best fit for breaking the trench stalemate.
