A)always clockwise
B)always counterclockwise
C)clockwise in the lower half of the loop and counterclockwise in the upper half
D)clockwise in the upper half of the loop and counterclockwise in the lower half
E)sometimes clockwise and sometimes counterclockwise

The direction of the induced current in a rotating loop within a magnetic field depends on the part of the rotation cycle the loop is in, due to the change in magnetic flux through the loop. This means the current's direction can switch between clockwise and counterclockwise as the loop rotates.
