💡 Analysis & Explanation

• **Determinant ▼

** Presence of specific **Antigens** (A and B) on the surface of Red Blood Cells (RBCs).

• **Genetics ▼

** Controlled by genes ($I^A, I^B, i$).

• **Options Analysis ▼

** Option A says 'Shape', B says 'Haemoglobin', C says 'Combination'. None accurately state 'Antigens on RBC'. However, if 'Shape/Structure' loosely implies surface properties, A is weak. 'None of the above' is technically precise because it's the *Antigens*, not shape.

• **Answer ▼

** D is the most scientifically accurate, though some loose keys might pick A.
