C right?

yes given answer is c

but MIME (Multi-Purpose Internet Mail Extensions) is an extension of the original Internet e mail protocol

Yes, but it isn't a protocol.

I mean, MIME by itself isn't the protocol. It's a standard used in the Email protocols.

on which layer MIME work?

It isn't a protocol. The question is asking for protocols.

MIME is an extension which allows SMTP to send non ascii based messages. so it is not a protocol by itself.
