Correct answer: C — Therapeutic anticoagulation unless contraindicated

Confirmed proximal DVT requires therapeutic anticoagulation unless bleeding risk is prohibitive. Aspirin alone is not definitive DVT treatment, and massage could theoretically dislodge thrombus. Thrombolysis is reserved for selected limb-threatening or extensive cases, not routine postoperative DVT.
