Imagine this scenario: You are having a conversation with someone about a tropical fruit which you have seen the picture of (on the internet or something) and do know the name of; but you have never seen or touched it in your hand or in a fruit market.
He: "What do you think of the papaya?"
You : "Oh... ?".
- oh, I've never seen it before
- oh, I've never seen it closely
- oh, I've never had it before
Which clearest answer emphasizing on just you have never seen in front of you(or touched) would be okay in this situation?
