Blood group B is characterized by the presence of antigen B on the surface of red blood cells (RBCs) and antibody 'a' (anti-A) in the blood plasma. Antibodies are not present on the surface of white blood cells (WBCs).

The possible genotypes for blood group B are $I^B{I}^B$ and $I^{B}i$, meaning it exhibits two types of genotypes.

Individuals with blood group B can safely receive blood from donors with blood group B and blood group O.

Therefore, the statement that antibody 'a' is present on the surface of WBCs is incorrect.

Answer: Antibody 'a' is present on the surface of WBCs
