Read the following statements.

Statement – I: Six phenotypes are observed for ABO blood groups 

Statement – II: Human ABO blood groups follow multiple allelism, codominance and dominance also. 

In light of the above statements, choose the correct answer from the options given below.

Six genotypes and four phenotypes are observed for ABO blood groups; ABO blood groupism is controlled by gene I with three alleles (multiple allelism), AB blood group is due to codominance, while A or B blood groups may be due to homozygous or heterozygous conditions (Heterozygous condition follows dominance)
