Two plane mirrors at an angle such that a ray incident on a mirror undergoes a total deviation of `240^(@)` after two reflections:

A

the angle between the mirrors is `60^(@)`

B

the number of images formed by this system will be 5, if an object is placed symmetrically between the mirrors

C

the number of images will be 5 if an object is kept unsymmetrical between the mirrors

D

a ray will retrace its path after 2 successive reflections, if the angle of incidence on one mirror is `60^(@)`
