Answer:
Option: B+
Explanation:
The test to determine a blood group is called ABO typing. The blood sample is mixed with antibodies against type A and B blood. Then, the sample is checked whether or not the blood cells stick together. If blood cells stick together, it means the blood reacted with one of the antibodies.
B+ blood group:
A blood sample that has only antigen B on the red blood cells and antibody A in the plasma lies under B+ blood group.
B+ blood type means the person has antigen B and rhesus factor on RBC and could be able to receive blood from another B+ donor.
Please note:
As only antigen B is mentioned that is why we will consider B+ BLOOD group. Because negative antigen is not mentioned in the question and when there is no sign is mentioned we will consider it positive.
