The use of -さん when answering about oneself?

Question

If someone says, > あなた は Chris-さん です か。 > Are you Chris? Do you answer > Chris です Or > Chris-さん です

Answer 1

さん is a suffix that roughly translated means "Mr." or "Ms.". It is an honorific to indicate respect when using one's name. It would be considered self centered and cocky to use it after your own name because it would be saying that you are in a place above them. so you are just "Chris です。” or even better would be to introduce yourself using your last name. First names are considered forward/intimate and less formal.
