You have been badly injured in a car accident．It is necessary to give you a blood transfusion because you lost a great deal of blood in the accident．However,special care must be taken in selecting new blood for you．If the blood is too different from your own,the transfusion could kill you.
There are four basic types of blood;A,B,AB and O．A simple test can indicate a person's blood type．Everybody is born with one of these four types of blood．Blood type,like hair color and height,is inherited from parents.
Because of substances contained in each type,the four groups must be trans fused carefully．Basically,A and B cannot be mixed．A and B cannot receive AB,but AB may receive A or
B．O can give to any other group,hence it is often called the universal donor．For the opposite reason,AB sometimes called the universal recipient．However,because so many reactions can occur in transfusions,patients usually receive only salt or plasma until their blood can be matched as exactly as possible in the blood bank of a hospital．In this way,it is possible to avoid any bad reactions to the transfusion.
There is a relationship between your blood type and your nationality．Among Europeans and people of European ancestry,about 42 percent have type A while 45 percent have type O．The rarest is type A
B．Other races have different percentages．For example,some American Indian groups have nearly 100 percent type O.
People with type A blood can receive__.
A、AB
B、B
C、O
D、None of the above
【正确答案】：C
【题目解析】：根据文章的内容，首先我们可以明确四种基本血型之间的输血规则：
* A型和B型血液不能相互输血。
* A型和B型血液不能接收AB型血液，但AB型血液可以接受A型或B型血液。
* O型血可以输给任何其他血型，因此被称为“万能供血者”。
* AB型血可以接受A型、B型或O型血，因此有时被称为“万能受血者”。
但是，在实际医疗操作中，为了确保输血的安全性和有效性，通常会尽量避免不同血型之间的输血，除非在紧急情况下没有其他选择。
具体到题目中的情况，一个A型血的人可以接收哪种血型的血液？根据输血规则，A型血的人只能接受A型血或O型血。而在给出的选项中：
A. AB - 不可以，因为A型血不能接收AB型血。
B. B - 不可以，因为A型血和B型血不能相互输血。
C. O - 可以，因为O型血是“万能供血者”，可以输给A型血的人。
D. None of the above - 不正确，因为C选项是符合输血规则的。
因此，正确答案是C，即A型血的人可以接收O型血。
