Options
A.the angle between the mirrors is 60o
B.the number of image formed by this system will be 5, if, an object is placed symmetrically between the mirrors
C.the number of image will be 5 if an object is kept unsymmetrical between the mirrors
D.a ray will retrace its path after 2 successive reflections s, if the incidence one mirror is 60o
