On every dial the long orange hand and the short dark hand move by fixed amounts from one cell to the next along a row. Which dial is missing?

Along each row the long hand turns a quarter turn clockwise (up, right, down) while the short hand turns an eighth of a turn anticlockwise (right, upper right, up). In the bottom row the long hand points right then down, so next it points left; the short hand points upper left then left, so next it points lower left: (a). (b) turns the long hand the wrong way, (c) turns the short hand clockwise and (d) swaps the two hands.
