Reply for thank you

[Ju]

When someone said thank you, what is the most polite way to reply in daily life?

E.g..

You're welcome
Don't mention it
It's ok
No worries
It's fine
My pleasure

Thanks.

When someone [STRIKE]said[/STRIKE] says "Thank you", what is the most polite way to reply in [STRIKE]daily life[/STRIKE] everyday situations?

E.g.

You're welcome. :tick:
Don't mention it. :tick:
It's [STRIKE]ok[/STRIKE] OK/okay. You'll hear it but "That's OK" is more common.
No worries. You'll hear it but it's not formal. For info, I associate with Australian English.
It's fine. :cross: We might say "That's fine".
My pleasure. :tick: Also "It's/It was my pleasure."

Thanks.

See above for my responses regarding the use of your suggestions in British English. The most formal, for me is "It's/It was my pleasure". As far as politeness goes, I would consider it polite to simply say something in response to "Thank you". However, a nod or a smile can be just as polite.
