The EMT shows that he can accurately differentiate placenta previa from abruptio placentae when he states:

A) "Abruptio placentae typically occurs in the first and second trimester; placenta previa occurs in the third trimester."
B) "Bleeding associated with abruptio placentae is typically associated with abdominal pain; bleeding associated with placenta previa is painless."
C) "Abruptio placentae rarely results in the death of the baby; the mortality rate of placenta previa is high."
D) "The blood lost with placenta previa is dark red; the color of blood associated with abruptio placentae is bright red."
