Correct answer: E — Apply separately, wait several minutes and let the family choose which product comes first

Explanation lettering: C = shown as A · E = shown as C · A = shown as E

A is correct. NICE advises applying one topical product at a time, waiting several minutes and allowing the family to choose which goes first. This avoids dilution or unpredictable formulation effects while keeping the regimen achievable. Mixing in the palm changes dose uniformity. A mandatory 12-hour separation undermines regular emollient use, while a universal 30-minute rule is not required by the current recommendation. Alternating days would undertreat an active flare. The more important safety issues are correct corticosteroid potency, site, duration and clear quantities.
