Ans. B. Henoch schonlein purpura
Explanation: An acute onset palpable purpura in the dependent regions like lower limbs and gluteal regions is very characteristic of HSP. It is usually seen in children between 2-10 years of age. Often associated with arthritis, abdominal pain, and elevated ESR and CRP with occasional renal involvement.
Meningococcemia can also present with acute onset purpura, but associated arthritis and a relatively stable child make HSP more likely.
ITP and scrub typhus do not usually present with palpable purpura and arthritis.
