Hello Rahul I think the answer to the third question may not be correct.Since from the third sentence which starts with our perception and ends in the seventh sentence I.e digital technologies it is clearly corelating with the perception of human life with digital technology and on defines the the other so the option that clearly explains that is , second option and the fourth option i think is invalid. Thank you.
I too feel its option B for 3rd question.

yes, the words "essential" & "mankind" are extremes used in the option about which the para doesn't talk about. I expected much more authentic & reliable key, specially for paper 2 as many found it tough
