The correct answer is option 4: B and AB.
Option 1 (A and O) is incorrect because blood type B contains antigens that can react with the antibodies in blood type A, potentially causing a harmful immune response.
Option 2 (B and O) is correct because blood type B can safely donate to individuals with the same blood type (B) and to individuals with blood type O, as blood type O is considered the universal donor for red blood cells without antigens A or B.
Option 3 (A and AB) is incorrect because blood type B contains antigens that can react with the antibodies in blood type A, potentially causing a harmful immune response.
Overall, option 4 is the correct answer, as blood type B can safely donate blood to individuals with blood types B and AB.
