The correct answer is: A. PQRS

The sentence is about the advantage of travelling. It says that the advantage of travelling is that we learn to appreciate the good points of others and our prejudice against them disappears. This is because travelling gives us the opportunity to observe people’s customs and manners in different places.

Option A, PQRS, is the only option that puts the words in the correct order to make a coherent sentence. Option B, QRSP, puts the word “we” at the beginning of the sentence, which is not grammatically correct. Option C, RSPQ, puts the word “and” after the word “disappears,” which is not grammatically correct. Option D, SPQR, puts the word “the” after the word “advantage,” which is not grammatically correct.

Therefore, the correct answer is A. PQRS.
