(  )

A.A型

B.B型

C.AB型

D.O型

答案

由分析可知,输血以输同型血为原则.但在紧急情况下,AB血型的人可以接受任何血型,O型血可以输给任何血型的人. 如果异血型者之间输血输得太快太多,输进来的凝集素来不及稀释,也可能引起凝集反应.因此,输血时应该以输入同型血为原则.异血型者之间输血,只有在紧急情况下,不得已才采用.任何血型的人都可以输入少量的o型血;AB血型的人,除可输入O型血外,也可以输入少量的A型或B型血.                   输血关系表

A       A  O      A  AB
B       B  O      B  AB
AB   A  B  AB  O       AB
O        O    A  B  AB  O
分析题意可知,该人可输入B型和O型血,但不能输A型血,说明他是B型血.

故选:B
