The orange cell follows a spiral path: clockwise round the outside of the board and then into the middle. It jumps the same number of cells each time. Where is it next?

Along the spiral the cell jumps 3 cells each step: top-left corner, top-right corner, bottom-right corner, bottom-left corner. Three more cells along the path go up the left edge to the second row and then turn right into the inner square: second row, second cell: (b). (a) moves only 2 cells and (c) starts the outer ring again instead of turning inwards.
