Question

suzanne has type a– blood. which blood type could she receive in a blood transfusion?
○ a+
○ o–
○ o+
○ b–

Explanation:

Blood transfusion compatibility: People with A- blood have A antigens and anti - B antibodies, and are Rh - negative. Rh - negative individuals can't receive Rh - positive blood (so A+ and O+ are out as they are Rh+). Also, they can't receive B - type blood (so B - is out) because of anti - B antibodies. O - is the universal donor for Rh - negative patients and is compatible with A - as it has no A/B antigens to trigger an immune response.

Answer:

B. O$-$
