Which of the following is a citrus fruit?

I'm not allowed to eat grapefruit

UnacknowledgedFrog3, Talk to your doctor. often a different drug can be given with the desired results, that does not conflict with grapefruit.

I thought it was apple

I'm not agree this...

Dadi♡Jael, this one is not on the topic, and it does not make sense

I thought strawberries have got a citric acid aswell
