The correct answer is 'ACDB'. Key Points The given question is an example of Sentence Jumble. We know that in a Sentence Jumbled Question the first sentence is usually an independent general statement, a universal fact, or starting of an incident, or it starts with a noun, most, once, etc.' Here, in the given question Only Part A can be the first sentence because it is the start of an incident and 'Dr. Prince' is a noun also. Part C is connected with Part A as Part C describes 'Dr. Prince' saw a girl of seven or eight. And Part D explains how that girl was staring at him or what she was doing Lastly, Part B will be used, because, what 'Dr. Prince' asked that Girl is shown. ​ Hence the correct order of sentences is: Dr. Prince became aware of a small figure standing in the aisle beside his seat. He brought his eyes into focus and saw that it was a girl of seven or eight. She was staring at him steadily with large blue eyes. “Won’t your mother be wondering where you are?” he asked her.
