Which option correctly matches Hertel exophthalmometry ranges by ethnicity?

Explanation:
Normal Hertel exophthalmometer readings vary by ethnicity because orbital anatomy and facial structure influence how far the globe sits forward. Using ethnicity-specific reference ranges helps distinguish normal variation from true exophthalmos. The commonly cited values are: Caucasian 12 to 22 mm, Asian 12 to 18 mm, and African American 12 to 24 mm. The option that matches these ranges is the one listing Caucasian 12-22, Asian 12-18, and African American 12-24. Remember that readings are still interpreted in the context of age, measurement technique, and individual variation.
