Ishika you are wrong. Try it yourself. When you move away from the mirror, it obviously will show more. And do not worry everyone, because it is just a printing mistake. And the answer is D. No matter what happens. It is only D. And, there is a sof account whose name is admin and he always answers computer questions correctly. He is appointed by sof only. All of his answers are called master answers. I think this is not fair. If you do not like that admin of sof, comment below. Thank you. Bye!

The beam of convergent light is the way the rays come from different directions which finally meet at a specific point, then that collection of the rays of light can be called as convergent rays or convergent beam of light . That is what happens with a pinhole camera A convergent beam of light enters the pinhole. So B is the correct answer.
