Final answer:
For an anterior pelvic tilt observed during a postural assessment, hamstring stretches are beneficial. This condition involves tight hip flexors and under-extended hamstrings, which contribute to the pelvis tilting forward.
Step-by-step explanation:
The compensation observed during a postural assessment that is most likely to benefit from hamstring stretches is A) Anterior pelvic tilt. This condition is characterized by the hip flexors being tight and the hamstrings being under-extended, which can contribute to the pelvis tilting forward. Stretching the hamstrings can help balance the muscles around the pelvis and improve this postural deviation.
