Final answer:
If Alex abducts her arm completely, she could have taken the action of raising her arm above her head.
Step-by-step explanation:
If Alex abducts her arm completely, she could have taken the action of raising her arm above her head (option a). Abduction refers to moving a body part away from the midline of the body. By raising her arm above her head, Alex is moving her arm away from the midline, which aligns with the concept of abduction.
