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!

Try standing in front of a mirror where only two-thirds of your body is visible. You will find it quite impossible to see the whole of yourself, even by moving away. that's why the answer is option c only.

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.
