‘R’ will be the first part of the given sequence as the pronoun ‘he’ refers to ‘Hiuen-tsang’ and moreover his decision to go to India was in the context of the fact that Buddhist text available in China were not sufficient (as stated in S1). ‘Q’ will come next as it tells that how he entered in India. ‘S’ will come next because it tells that where he decided to go after visiting India. P will pair with S6 as P tells that he was asked to stay wherever he went and S6 tells that he could not stay anywhere because he was on a quest. Hence, RQSP is the right sequence. Thus, option (d) is correct.
