The passage discusses the story of a famous 3.3 m elephant born in Africa. R will be the first sentence in the arrangement as it highlights its transportation from Africa, his native land. RS is a mandatory pair as they are highlighting the admirers of Jumbo. 'Q' will be followed by 'S' as the story continues with other transportation abroad to New York. 'P' will naturally become the last sentence. The correct sequence will be 'RQSP'. So, option (d) is correct.
