Question

suzanne has type a– blood. which blood type could she receive in a blood transfusion?\
\\(\bigcirc\\) a+\
\\(\bigcirc\\) o–\
\\(\bigcirc\\) o+\

Explanation:

O- is the universal donor for negative blood types, as it has no A/B antigens and no Rh factor, so it won't trigger an immune reaction in A- recipients. A+, O+, and B- have antigens (Rh+ or B) that would cause a reaction in an A- person.

Answer:

O-
