which is qhe correct way to ask and why

[Secondtongue]

I have seen the same question but written in a different way. I guess only one of the following is grammatically correct. Please tell me which and why?
a. What did you say was your name?
b. What did you say your name was?

It seems that both a) & b) in fact consists of 2 questions, "What is your name?" & "What did you say?". Is better not to merge 2 questions into one?

Both forms of the question are fine.

The reason for "say" in this question is that you did not hear or understand what the person said the first time.

it would be impolite in this context merely to ask "What did you say?".

Thank you but I think only one of them is grammatically correct because I saw the above in a multiple choice question (I don't remember which examination paper).

A is acceptable in colloquial speech
B is always correct
What I hear is "What did you say your name was (again)?";-)
