The tail rotor provides

The tail rotor provides anti-torque and directional control Lift Fuel supply Navigation lights

Correct Answer:

Fuel supply

Explanation:

The tail rotor’s job is to counteract the torque produced by the main rotor and to provide yaw control. When the main rotor spins, the fuselage tends to rotate in the opposite direction. The tail rotor generates thrust to balance that torque, and by varying its thrust, the pilot can rotate the helicopter’s nose to change heading. Lift comes from the main rotor, not the tail rotor. The tail rotor doesn’t supply fuel, which comes from the engine’s fuel system, nor does it handle navigation lights, which are separate avionics.
