Answer

Brief Explanations:

The discovery of four blood - types in 1898 and wartime advancements led to improved transfusion safety, development of preservation solutions, and ability to separate blood components. But all blood types are not made universally compatible. There are still donor - recipient compatibility rules based on blood type (e.g., type O is a universal donor for red blood cells to some extent, but not for all blood components and not completely universal in all situations).

Answer:

all blood types were made universally compatible
