Answer:

B. O−

Explanation:

Step1: Understand blood - type compatibility

Blood type A− has A antigens and anti - Rh antibodies.

Step2: Analyze each option

A+ has Rh factor which will cause a reaction with anti - Rh antibodies in A− blood. O+ has Rh factor which will cause a reaction. B− has B antigens which will react with anti - B antibodies in A− blood. O− has no A, B antigens and no Rh factor, so it is compatible with A− blood for transfusion.
