question 13
an individual whose blood type is b- can receive blood from which of the following

1. o+
2. ab-
3. b+
4. o-

Explanation:

Blood transfusion compatibility is based on the presence or absence of certain antigens (A, B, Rh factor). A person with blood type B - has B antigens and no Rh factor. They can receive blood from donors who do not have A antigens (to avoid immune reaction) and also no Rh factor (since they are Rh -).

• Option 1: O+ has Rh factor (incompatible as recipient is Rh -).
• Option 2: AB - has A antigens (incompatible as recipient has B antigens, immune reaction would occur if A antigens enter).
• Option 3: B+ has Rh factor (incompatible as recipient is Rh -).
• Option 4: O - has no A or B antigens and no Rh factor (compatible).

Answer:

1. O -
