Explanation:

Step1: Analyze Type AB+

• AB+ blood type has A and B antigens (agglutinogens) on red blood cells. So, "Expresses the A agglutinogen" and "Expresses all of the major antigens" (A and B antigens are major in ABO system) go to Type AB+.
• AB+ is the universal recipient as it has no antibodies (agglutinins) against A and B in its plasma to react with donor's A or B antigens. So, "The universal recipient" goes to Type AB+.

Step2: Analyze Type O -

• O - blood has no A or B antigens on red blood cells. It has anti - A and anti - B antibodies (agglutinins) in plasma. But "Expresses all of the major antibodies" is incorrect as major antibodies in ABO are anti - A and anti - B, but O - has them. However, O - is the universal donor as its red cells have no A or B antigens to cause reaction in recipient. Also, "The most common U.S. blood type" is O (but not sure if this is a distractor here, but based on blood type facts, O - is a subset of O. If we assume the intended match: "The universal donor" goes to Type O -.

Answer:

Type AB+: Expresses the A agglutinogen, The universal recipient, Expresses all of the major antigens
Type O -: The universal donor
