b. Anti A, anti Rh
c. Anti A
d. Anti B, anti Rh
e. Anti B

Step 1: Understand the blood type notation. Blood type A means the person has A antigens on the surface of their red blood cells. Rh⁺ means the person has the Rh (D) antigen present.
Step 2: Recall that naturally occurring antibodies in the serum are directed against antigens that the person does NOT have on their red blood cells. Since this person has A antigens, they will NOT have anti-A antibodies.
Step 3: Since the person has A antigens, they will naturally produce anti-B antibodies, because B antigens are foreign to them.
Step 4: For the Rh factor, a person who is Rh⁺ has the Rh antigen, so they will NOT have anti-Rh antibodies naturally. Anti-Rh antibodies develop only after exposure to Rh-positive blood if the person is Rh-negative.
Step 5: Combine these facts: the person with blood type A, Rh⁺ will have anti-B antibodies naturally, but no anti-A or anti-Rh antibodies. Therefore, the correct antibodies found naturally in their serum are anti-B only.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

ABO Blood Group System

The ABO system classifies blood types based on the presence or absence of A and B antigens on red blood cells. A person with blood type A has A antigens on their cells and naturally produces anti-B antibodies in their serum to target B antigens.

Rh Blood Group System

The Rh system is determined by the presence (Rh⁺) or absence (Rh⁻) of the Rh(D) antigen on red blood cells. Individuals who are Rh⁺ do not naturally produce anti-Rh antibodies, while Rh⁻ individuals may develop anti-Rh antibodies after exposure to Rh⁺ blood.

Natural Antibodies in Blood Serum

Natural antibodies are those produced without prior sensitization, typically targeting antigens absent on an individual's own red blood cells. For example, a person with blood type A naturally has anti-B antibodies, but not anti-A or anti-Rh antibodies if Rh⁺.
