Correct Answer - B
(b) The number of images formed depends upon the angle between the mirrors. If two mirrors make an angle `theta` with each other, then the number of images formed is
`n=360^(@)/theta-1`
when mirrors are kept mutually perpendicular to each other, then `theta=90^(@)`
`n=360^(@)/90^(@)-1=3`
