Final answer:
Individuals must inherit both the Le and Se genes to express the Le(b) antigen on red blood cells; thus, the answer is 'D. All of the above' if 'All of the above' encompasses both genes being necessary.
Step-by-step explanation:
To express the Le(b) antigen on red blood cells, an individual must inherit specific genes related to the Lewis blood group system, which is separate from the ABO and Rhesus blood group systems. While the question does not provide the specific genetic notation typically used for the Lewis blood group, it is generally known that the Le gene is responsible for the production of the Lewis antigens. Individuals who inherit this gene and also possess the Se gene (which dictates secretor status) can express Le(b) antigen on their red blood cells.
Therefore, genes Le and Se are required for an individual to express the Le(b) antigen on their erythrocytes. It's not directly related to the alleles for the ABO blood group (IA, IB, i) or the RHD and RHCE genes of the Rhesus blood group system. Thus, the correct answer is 'D. All of the above', assuming that by 'All of the above', the question is referring to the necessity of having both Le and Se genes.
