A All of the above
Explaination
The generated force on a current carrying wire is directly proportional to the amount of current flowing, the length of the wire, and the strength of the magnetic field. Increasing any of these will increase the force on the wire and the capacity to do work.
B Increasing the amount of current flowing.
C Decreasing the length of the wire.
D Decreasing the strength of the magnetic field.
