To make a lever system more efficient, the best option from the choices provided is:
**Use a stiffer lever to reduce energy lost bending the lever.**
A stiffer lever will minimize energy lost due to bending and deformation, which can contribute to inefficiency in the system. While the other options may help in different ways, increasing the stiffness of the lever directly addresses the efficiency issue by reducing energy losses.
