I am completely shocked. How can SOF make such errors in almost every subject!? There are ONLY 3 pairs in the question which have the same number of letters as in the alphabet: ON, DE and RS. There is no fourth pair in the image. Therefore, the answer should be Option C and not Option D. I request SOF to PLEASE RECTIFY THE ERRORS.

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.

The answer can be c according to the size of the mirror. As the size is not mentioned , I think that the answer should be d.....

Ans 18:

Class : Class 10
I think that the correct option should be D

Ans 19:

Class : Class 7
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.
