In which of the following passages does O'Brien convey a nostalgic tone toward Linda?
A. That night, I remember, she wore a new red cap, which seemed to
me very stylish and sophisticated, very unusual.
B. She started to say something but then hesitated. Frowning, she
squinted out at the field for a second, then shrugged and walked
back to the jeep.
C. She never took it off, not even in the classroom, and so it was
inevitable that she took some teasing about it.
D. She had long white legs and blue eyes and a complexion like
strawberry ice cream. Very friendly, too.
