‘P’ will be the first part of the given sequence as ‘he’ introduces the subject. ‘S’ will follow next as ‘barely five feet’ is used in relation to ‘a tiny man’ in the very previous part. It will immediately be followed by ‘R’ as ‘five feet tall’ forms a logical pairing together and hence giving the information about the man’s height. ‘Q’ will be the last part of the given sequence as it tells the style of his walk, that is, “a sprightly walk’. Hence, PSRQ is the correct sequence. Thus, option (d) is correct.
