The point $(4,1)$ undergoes the following transformations successively:
$I$. Reflection about the line $y=x$.
$II$. Translation through a distance $2$ units in the direction of the positive $X$-axis.
$III$. Rotation through an angle $\frac{\pi}{4}$ about the origin in the anticlockwise direction.
Then,the final position of the point is:

  • A
    $\left(\frac{7}{\sqrt{2}}, \frac{1}{\sqrt{2}}\right)$
  • B
    $(\sqrt{2}, 7\sqrt{2})$
  • C
    $(-\sqrt{2}, 7\sqrt{2})$
  • D
    $\left(\frac{1}{\sqrt{2}}, -\frac{7}{\sqrt{2}}\right)$
