Which of the following answer figure completes the series of the question figure?

Triangle is moving one step from one box to the other one in a clockwise direction after the rotation of 90$$^{\circ\ }$$ in the clockwise direction. By this logic, options (b), (c) and (d) can be eliminated. Now only option (a) is remaining which can come in place of the question mark.

Circle is moving one step from one box to the other one in a clockwise direction after the rotation of 180$$^{\circ\ }$$.
