‘S’ will be the first part of the given sequence as it tells the condition of the traveller, that is, “being weary”. PQ will make a pair together because it tells that he ‘sat down to rest’. ‘R’ will be the last part of the given sequence as it tells the place where the traveller sat down, that is, by the roadside. Hence, SPQR is the correct sequence. Thus, option (c) is correct.
