Answer:
A. Fuller pillows that keep her neck straight.
Step-by-step explanation:
Flat pillows can cause neck and back pain, as they do not provide adequate support for the head and neck. A fuller pillow will help keep the neck straight, promoting better alignment of the spine and reducing the risk of discomfort or injury. Stacking pillows may provide temporary relief, but it is not a long-term solution and may not provide the necessary support for the head and neck. Eliminating pillows altogether may be uncomfortable for many people and may cause strain on the neck and back. Using the pillows to get her feet higher than her head is not a recommended solution for better sleep posture.
