D. Vasa previa
CORRECT ANSWER: B
RATIONALE:
Placenta previa is characterized by painless, bright red vaginal

contrast, abruptio placentae typically presents with painful, dark
red bleeding and a rigid, board-like uterus.

sudden onset of intense abdominal pain, uterine tenderness, and
a firm, rigid, board-like abdomen.
