A uniform magnetic field \( B \) is directed out of the page. A metallic wire has the shape of a square frame and is placed in the field as shown. While the shape of the wire is steadily transformed into a circle in the same plane, the current in the frame
(a) Is directed clockwise
(b) Does not appear
(c) Is directed counterclockwise
(d) Is alternating
