Are there any of the following answers wrong and why? How do you usually answer that question if there is a need to answer especially politely?
Would you like a piece of cake or a candy bar?
Either of them will be fine.
Either of them is fine.
I would like either of them.
Best Answer
In this context fine means good or satisfactory and would be deemed offhand. So your first two sentences would be more suitable when choosing, say, a ladder.
At my politest I'd probably say, 'Thank you. I'd like either.' More effusively I might prefix an 'Ooh!' or a 'How lovely!' or both.
