I asked you how. Do you have an explanation?
In order to fit your story we must accept that God, for that period of time, waited with baited breath to see what Mary would do.
Do you understand that God s outside of time? He didn't have to "wait" for anything.
It means she had no choice. Maybe she was free to choose her breakfast but not free to deny God. She was chosen to be the mother of Jesus and the angel was sent to tell her so.
You have not even tried to explain why she was not free. Being Immaculately Conceived means that she had no Original Sin. It doesn't mean she has no free will. Adam and Eve had no OS and they chose to ignore God. Mary had no OS and she chose to obey God.
Why do you think the lack of OS makes a person not have a free will?

Christians believe Mary was chosen by God to be the mother of Jesus.
Some Christians believe she was chosen, and the only one chosen to be Immaculately Conceived, in order to be the mother of Jesus.
Only one person chosen by God to be the mother of Jesus, only one Jesus. NO CHOICE! It is written!
