A) Life-threatening hemorrhagic coagulopathy 
B) High risk of massive Pulmonary Embolism
C) Cardiogenic shock
D) Neutropenic fever, sepsis and death

Answer: A

Acute promyelocytic leukemia (APL) is a medical emergency due to its characteristic coagulopathy, causing fatal hemorrhage. Though aggressive transfusions of platelets and cryoprecipitate may help but mainstay of treatment is initiation of treatment with all-trans retinoic acid (ATRA) ASAP even though definitive confirmation of the diagnosis is not  made.
