The Flight Attendant Told Her Passengers That 90% of Those

The flight attendant told her passengers that 90% of those passengers who reported that they had listened to the instructions of what to do in the unlikely event of a crash landing survived such a crash landing. Has the flight attendant made a thinking error?

A) No, because this is very useful information to impart to her passengers.
B) No, by citing an exact percentage she is being precise and not showing vagueness in her description.
C) Yes, because this information is based on an inadequate comparison since people who died could not provide a report.
D) Yes, because the attendant is equivocating on the meaning of the word "survived."
