If the propeller rotates counterclockwise, it is described as what?

Propeller handedness is defined by the direction of rotation when you look at the propeller from the drive end (the engine side). A left-handed propeller spins counterclockwise from that viewpoint, while a right-handed one spins clockwise. So when the propeller rotates counterclockwise as you observe from the drive end, it’s described as left-handed. This matters because the rotation direction affects torque and thrust, and is used to balance propulsion in setups with multiple propellers. The other options don’t fit because right-handed would be clockwise from the drive end, neutral implies no preferred direction, and bi-directional would mean it can rotate both ways, which isn’t what a single rotation direction indicates.
