A point source is placed at co-ordinates (0,1), in X-Y plane. A ray of light from the source is reflected on a plane mirror placed along the X-axis and perpendicular to the X-Y plane. The reflected ray passes through the point (3,3). What is the path length of the ray from (0,1) to (3,3)?

A

5

B

`sqrt(13)`

C

`2sqrt(3)`

D
