The correct option is
A RPSQ
The proper sequence is RPSQ. Let us see why.
The sentence starts with 'Everyone', which is the subject. The phrase (R) i.e 'who knows you' describes the subject. Hence, it has to immediately follow the subject. The first part of the sentence is: 'Everyone who knows you'.
The next part which follows has to contain the verb which the subject does. The word, 'everyone' is a singular noun which has to be followed by a verb+'s'. The word 'acknowledges' in (P) appropriately indicates a verb which can follow the noun, 'everyone'. Hence (R) is followed by (P).
The next part should answer the question, 'What does everyone acknowledge?'. The answer lies in part (S) i.e 'that you have been wronged'. Hence, (P) is followed by (S).
The phrase, (Q) 'when he considers this case calmly' is an adverbial phrase of time which describes the time when 'Everyone who knows you acknowledges that you have been wronged'. Hence, (S) is followed by (Q).
So, the correct sentence is: 'Everyone (R) who know you (P) acknowledges (S) that you have been wronged (Q) when he considers this case calmly'.
Hence, option A i.e RPSQ is correct and the other options B, C and D are incorrect.
