I believe it is answer 3 "Appointment, concerns"
1 is wrong because reservation doesn't mean "Making a special exception" and concern, and appointment do.
2 is wrong also for that reason
3 is right because you're making an appointment at the restaurant, but the reviews give me some concerns.
4 is wrong, because it is the other way around.
Therefore, the right answer is 3 appointment, concerns
