Based on Shondra's interests in justice, safety, fairness, physical fitness, and her ability to handle risky high-pressure situations, the three career clusters she would be well suited for are:
- Law - Since she is passionate about justice and fairness.
- Public Safety - Given her interest in safety and ability to handle high-pressure situations.
- Physical Education - Considering her enjoyment of physical fitness.
Security could also be a relevant option, but it's less aligned with her interest in justice compared to the other three.
