Correct answer: D — Immune complex glomerulonephritis after group A streptococcal infection

Post-streptococcal glomerulonephritis is an immune complex process following group A streptococcal infection, with haematuria, hypertension and low C3. Direct bacterial invasion is not the mechanism. Monitoring blood pressure, renal function and fluid status is central.
