Gerund vs Infinitive

[yun]

I have two questions about following two sentences

(A) The doorman held the door for her passing through.
(B) The doorman held the door for her to pass through.

Q1. If both sentences are grammatically correct?
Q2. If they are, what is the difference in the meaning?

Thank you.

Thank you for your prompt reply.
Would you explain the reason?
In fact, I can't see any grammatical problem.

A is correct.

The question is whether you would say like that, svartnik.

A is correct.

Are you a native speaker?
I am sorry but I need a serious answer with a grammatical explanation.

I don't like either of them. They both seem to indicate that the lady is going to pass through the door that the doorman is holding, rather than through the doorway. Is she in spirit?
The doorman held the door while she walked through.
I know this could also be read wrongly, but there's something about the original expression that invites the above interpretation.

Bhai, the 'passing' in 'passing through' is a gerund.
The police cleared the road for the Queen's passing by.

Would you say: The police cleared the road for the Queen's passing by.
or: The police cleared the road for the Queen's entourage to pass by.
