b. Usually develops after 3 weeks of blood transfusion
Post-transfusion purpura (PTP) typically develops within 5 to 10 days after a blood transfusion, not 3 weeks. It is most commonly caused by anti-HPA-1a antibodies, and the treatment of choice is intravenous immunoglobulin (IVIg). Even HLA-matched platelets are not effective in this condition.
