Final answer:
After treatment, lice should be inspected for at least 2 weeks to ensure complete elimination.
Step-by-step explanation:
After treatment, it is important to inspect for lice to ensure that all the lice and their eggs (nits) have been eliminated. The recommended duration for inspection varies depending on different sources, but generally, it is recommended to inspect for at least 1-2 weeks after treatment. This is because lice eggs can take around 7-10 days to hatch, and inspecting for a longer period helps to catch any newly hatched lice before they can reproduce and cause infestation again.
So, the correct answer would be d) 2 weeks after treatment.
