The correct answer is D. According to aviation security regulations, passengers with prosthetics are not exempted from security screening.
All passengers are subject to security screening. For passengers with medical implants or prosthetics, modified screening procedures are followed to ensure both security and the dignity/comfort of the passenger. This might involve a combination of walk-through metal detectors, hand-held metal detectors, pat-down searches, and visual inspection, potentially in a private screening area. Exemption is not provided.
The specific procedures are designed to address the potential for metallic components in prosthetics triggering alarms while still ensuring that no prohibited items are concealed. Screening is mandatory regardless of medical condition or alert level.
