The correct explanation for Sam's blood group being AB+ while his father has A+ and his mother has B+ is:

**B: combination of different genes for the blood of parents during reproduction.**

Blood type inheritance is determined by multiple alleles, where type A and type B are co-dominant and type O is recessive. Sam inherits one allele from each parent—a type A allele from his father and a type B allele from his mother—resulting in the AB blood type.
