Answer:
D. Good intentions do not always lead to desirable outcomes.
Explanation:
Here in the question, it is evident that in order to protect the children from poisoning themselves, the government took a good step by passing a regulation to put child-resistance safety caps on the pill bottles.
But it is also evident that this regulation back fired and caused more casualties than before due to the non serious behavior of the general public.
Hence it can be concluded that the government put a good intention but it did not lead to the desired outcome for the government.
Hope I made myself clear buddy.
Good Luck.
