Which blood type can be transfused into a patient who has blood type A–?
Oksana_A [137]

For a person with blood type A- (A negative),  they can be transfused with either  blood type A negative  , or blood type O negative.

This is because any other blood type will immediately be rejected by their body.

A person with blood type A negative has got antibodies against any other blood type which has a rhesus positive factor as well as antibodies against  any other blood type of a different group such as B and AB, even if they are  rhesus negative.

Therefore because of the rhesus negative factor, a person with blood type A negative  can only be transfused with rhesus negative .

For this, some rules or phases are part of the process. And they are: observation, hypotheses, research method and conclusion.

Thus, we can conclude that among the alternatives presented, the one that best describes the logic of scientific investigation is the letter D.
