A) remains stationary
B) moves forward or backward
C) moves up or down, depending on the direction that the knob is turned
D) moves left or right, depending on the direction that the knob is turned

Accepted Answer

The coarse adjustment knob is responsible for moving the stage (or nosepiece) up and down to bring the specimen into focus. Therefore, as the knob is turned, the stage should move up or down (depending on the direction that the knob is turned) to allow for proper focusing. It should not remain stationary or move left or right.
