\(AB\) રુધિરજૂથ ધરાવતી વ્યક્તિ સર્વગ્રાહી કહેવાય, કારણ કે …..

A રક્તકણ ઉપર \(A\) અને \(B\) ઍન્ટિજન આવેલા પરંત રુધિરરસમાં ઍન્ટિબૉડીનો અભાવ હોય.
B રુધિરરસમાં ફક્ત \(A\) અને \(B\) એન્ટિબૉડી આવેલ હોય.
C \(RBC\) પર ઍન્ટિજન અને રુધિરરસમાં ઍન્ટિબૉડીનો અભાવ હોય.
D રુધિરરસમાં \(A\) અને \(B\) ઍન્ટિજન આવેલા પરંતુ ઍન્ટિબૉડીનો અભાવ હોય.

Verified Solution

Answer & Solution

Correct Answer

(A) રક્તકણ ઉપર \(A\) અને \(B\) ઍન્ટિજન આવેલા પરંત રુધિરરસમાં ઍન્ટિબૉડીનો અભાવ હોય.

Step-by-step Solution

Detailed explanation

(a) : Individuals with \(AB\) blood group have both antigen \(A\) and \(B\) on their \(RBCs\), and no antibodies for either of the antigen in their plasma. Type \(O\) individuals are without \(A\) and \(B\) antigens on their \(RBCs\), but have antibodies for both these antigens in their plasma. Individuals with blood group \(AB\) can receive blood of \(A, B\) or \(O\) group, while those with blood group \(O\) can donate blood to anyone.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
