Answer: Responsible
Explanation: Because being careless would mean they would be doing it without caring why they are doing it so that's not the right option. Convenient would mean they are doing it just because they have the opportunity and if that was the case many companies could have done it before so that's not right. Desperate would mean they are doing it because they really need to do it and they really need to succeed because they are losing hope over something and that is not what I read in the text. So my answer is responsible because they are making the right choice for the safety and health of the kids because they consider it an obligation to protect the kids.
