if you need to review this content, it can be found in the awkward and static positions module of the ergonomics topic.

Explanation:

Mary sits for long periods (with limited breaks) at a computer. Static posture hazard occurs when a person holds the same position for extended time, which matches Mary’s situation (prolonged sitting without much movement). Contact stress involves pressure from hard surfaces, awkward posture is non - neutral body positions (not indicated here as she’s just sitting), and vibration isn’t present in a typical computer - inputting job.

Answer:

A. Static posture
