Final answer:
Option (A), The muscles contributing to spinal stabilization and alignment include the transversus abdominis, internal oblique abdominal, and deep lumbar multifidus.
Step-by-step explanation:
The muscles that contribute to spinal stabilization and alignment include a variety of muscle groups that work together to support the vertebral column. In the anterior and lateral abdominal wall, you have three layers of muscles: the external oblique, the internal oblique, and the deepest layer which is the transversus abdominis. These muscles work in concert to aid in trunk movements and provide stability to the lumbar spine and protect the internal organs.
Specifically, the internal oblique abdominal and transversus abdominis play vital roles in spinal stabilization. Additionally, the deep lumbar multifidus muscle, part of the transversospinales group, is essential for extending and laterally flexing the vertebral column as well as providing segmental stabilization. Therefore, the correct answer is A. Transversus abdominis, internal oblique abdominal, and deep lumbar multifidus.
