الإجابة: B. Low molecular weight heparin
In cancer-associated DVT (active breast cancer on chemotherapy) the cohort notes say to treat with LMWH alone; Step Up also names LMWH as a preferred agent. Warfarin is harder to keep therapeutic with chemotherapy, UFH is for inpatient/renal failure situations, and dabigatran needs heparin lead-in and is not the cancer-VTE choice in the sources.

A
ليش غلط
Dabigatran needs dual therapy with heparin at initiation, so it is not a simple single-agent choice.

C
ليش غلط
UFH is an inpatient IV infusion needing frequent monitoring, preferred for hemodynamically unstable PE; this patient is hemodynamically stable.

D
ليش غلط
Warfarin requires INR monitoring and is difficult to keep in the therapeutic range, so it is less often used than DOACs.
