It’s not so easy.
She could not have said no.
Read Luke 1:31
That doesn’t sound like a request to me.
I’m ending it here - it’s too off topic.

This is not Catholic teaching. Mary wasn’t cattle she was a fully human being which requires free will. You must also believe that Judas didn’t have free will when he betrayed Jesus?
CCC(my emphasis)
484 The Annunciation to Mary inaugurates “the fullness of time”,119 The time of the fulfilment of God’s promises and preparations. Mary **was invited **to conceive him in whom the “whole fullness of deity” would dwell “bodily”.120 The divine response to her question, “How can this be, since I know not man?”, was given by the power of the Spirit: "The Holy Spirit will come upon you."121
488 “God sent forth his Son”, but to prepare a body for him,125 he wanted the
free co-operation of a creature. For this, from all eternity God chose for the mother of his Son a daughter of Israel, a young Jewish woman of Nazareth in Galilee, “a virgin betrothed to a man whose name was Joseph, of the house of David; and the virgin’s name was Mary”:126
The Father of mercies willed that the Incarnation should be preceded by assent on the part of the predestined mother, so that just as a woman had a share in the coming of death, so also should a woman contribute to the coming of life.127
490 To become the mother of the Saviour, Mary "was enriched by God with gifts appropriate to such a role."132 The angel Gabriel at the moment of the annunciation salutes her as “full of grace”.133 In fact,
in order for Mary to be able to give the free assent of her faith to the announcement of her vocation, it was necessary that she be wholly borne by God’s grace.
494 At the announcement that she would give birth to “the Son of the Most High” without knowing man, by the power of the Holy Spirit, Mary responded with the obedience of faith, certain that “with God nothing will be impossible”: "Behold, I am the handmaid of the Lord; let it be [done] to me according to your word."139
Thus, giving her consent to God’s word, Mary becomes the mother of Jesus. Espousing the divine will for salvation wholeheartedly, without a single sin to restrain her, she gave herself entirely to the person and to the work of her Son; she did so in order to serve the mystery of redemption with him and dependent on him, by God’s grace:140…
511 The Virgin Mary “co-operated through **free faith **and obedience in human salvation” (LG 56). **She uttered her yes **“in the name of all human nature” (St. Thomas Aquinas, S Th III, 30, 1). By her obedience she became the new Eve, mother of the living.
The idea that Mary could not say no is in my opinion a heresy.
