Let Tk be the transformation of the coordinate plane that first rotates the plane k degrees counterclockwise around the origin and then reflects the plane across the y-axis. What is the least positive integer n such that performing the sequence of transformations transformations T1,T2,T3,…,Tn returns the point (1,0) back to itself?<spanclass=′latex−bold′>(A)</span>359<spanclass=′latex−bold′>(B)</span>360<spanclass=′latex−bold′>(C)</span>719<spanclass=′latex−bold′>(D)</span>720<spanclass=′latex−bold′>(E)</span>721
