‘Q’ will be the first part of the given sequence as it is in continuation with the previous statement and describes the subject mentioned in detail which is clear from the words, ‘It was a shop’. ‘S’ will come next as it is in continuation with the previous statement which is clearly indicated from the word, ‘and’. ‘P’ will follow next as it refers back to the previous statement which is clear from the word, ‘therefore’. ‘R’ will follow logically as it begins with the pronoun, ‘he’ that refers back to the man talked about in the previous statement. Hence, QSPR is the correct sequence. Thus, option (d) is correct.
