V2 is defined as?

• A. The takeoff safety speed.
• B. The speed at which to lower landing gear.
• C. The stall speed in a takeoff configuration.
• D. The minimum climb speed after takeoff.

Answer: (A)

V2 is the takeoff safety speed—the minimum speed at which the airplane can safely continue the takeoff after an engine failure and still meet the required initial climb performance with one engine inoperative. This speed gives you enough control authority and climb capability to ensure a safe OEI (one engine inoperative) takeoff, including maintaining the necessary climb gradient and avoiding a stall or loss of control.

It's higher than the stall speed in takeoff configuration, providing a safety margin. It isn’t the speed to lower the landing gear (gear extension uses a different V-speed), nor the stall speed in takeoff configuration itself, nor just a generic “minimum climb speed after takeoff.” So the takeoff safety speed best fits what V2 represents.
