Which item is explicitly listed as a RCDAD with Xenotransplantation risk?

• A. Xenotransplantation risk
• B. Seasonal allergy
• C. Obesity
• D. Vitamin deficiency

Answer: (A)

The key idea here is recognizing an item that directly names the specific risk category. The option that explicitly says xenotransplantation risk is the one that matches the RCDAD listing for that risk. In this context, RCDAD is used to flag particular risks, so the only choice that directly references xenotransplantation risk is the explicit listing itself. The other options—seasonal allergy, obesity, and vitamin deficiency—do not pertain to xenotransplantation risk and wouldn’t be identified as the xenotransplantation RCDAD.
