b. more soldiers who had lost a limb returned home.
c. more donations were needed as a result of poor storage techniques.
d. more organizations spoke out against the war.

Answer;

More soldiers who had lost a limb returned home.

Explanation;

-Blood transfusion had been attempted throughout history but generally failed due to a variety of factors. Chief among these was the propensity of blood to clot, reducing its flow and clogging equipment used to transfer it. Blood could not be stored and needed to be administered as quickly as possible.

-The First World War introduced transfusion methods to more doctors and in more standardized procedures than might have occurred in peacetime, and convinced them of its benefits. When these physicians returned home, blood transfusion gained a new place in civilian medical practice.
