Venus is the hottest planet in the solar system. Although Venus is not closest to the sun, its dense atmosphere traps heat. As a result, temperatures on Venus are higher than the temperature on Mars.

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!

Ans 23:

Class : Class 7
It's D for heaven's sake THEY CAN'T MAKE IT PROPERLY THEY SHOULDN'T MAKE IT. As you can see the light reflects from the mirror but avoids the eye how will you see the object

Ans 28:

Class : Class 4
Hey!!!!! Not fair it should be D!!!

Ans 30:

Class : Class 5
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.
