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.

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 5:

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.

Ans 6:

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!

The answer is convergent,but what's its meaning?

Ans 2:

Class : Class 6

Ans 3:

Class : Class 7
what is the correct answer?

Ans 4:

Class : Class 9
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.

Ans 5:

Class : Class 9
