| A) Increasing the proportional gain without limit will always decrease the steady-state error. |
| B) Increasing the proportional gain without limit will always increase the steady-state error. |
| C) Increasing the proportional gain within limits will decrease the steady-state error, but too much gain may cause instability. |
