Final answer:
People with type B+ blood can receive donations from B+, B-, O+, and O- blood types, with type O- being the universal donor.
Step-by-step explanation:
Individuals who have type B+ blood can receive donations from those with type B or type O blood, with compatible Rh factors. Blood type B can receive from B and O types because these do not have antigens that would cause an immune reaction. Because people with B+ blood also have the Rh factor, they can receive blood from donors who are Rh-positive (B+ or O+) or Rh-negative (B- or O-).
Therefore, the blood types that can donate to a person with B+ blood are B+, B-, O+, and O-. Notably, type O- is known as the universal donor and can donate to any other blood type, which includes B+ individuals.
