Correct answer: D — IM adrenaline 0.01 mL/kg of 1:1000

Anaphylaxis requires immediate IM adrenaline (0.01 mL/kg of 1:1000, max 0.5 mL) injected into the mid-anterolateral thigh. This is the first-line treatment and should not be delayed. IM adrenaline can be repeated every 5 minutes if needed. IV adrenaline is reserved for refractory cases in a monitored setting.
