choose all the blood types of individuals that will have anti-a agglutinins in their plasma.

□ type ab
□ type b
□ type o
□ type a

Explanation:

To determine which blood types have anti - A agglutinins:

• Type AB: Has A and B antigens, so no anti - A (would agglutinate own A antigens).
• Type B: Has B antigen, so has anti - A (to not agglutinate own B antigen and react against A).
• Type O: Has no A or B antigens, so has anti - A and anti - B (to react against A and B antigens from others).
• Type A: Has A antigen, so no anti - A (would agglutinate own A antigens).

Answer:

B. Type B, C. Type O
