I think it is C, since it sounds the most reasonable.
Answer:
drink more water, get a massage
Explanation:
The real solution isn't banning them. People aren't the ones who dump them in to the oceans. Yet sometimes they do on beaches. The ones who dump them are corporate companies. We need to enforce laws saying that dumping is bad, and maybe a humongous fine like 10 billion, to scare away corporate dumpster companies away from the seaside
Individual decision making is more limited than collaborative decision making because as an individual you would only have one or two points of view on the subject as well as knowledge and ideas. If you were to work with more people to decide on something then there would be a good chance that everyone would be able to pitch in ideas and different points of views to overall decide.
The first thing I would do is try organize a game possibly. A game where each round kids who win said game, get to play with toys on one side of the area, while the other kids get to sing songs, tell jokes, etc. (if they are allowed to do this)
Maybe you could create a song.
This song would remind kids to not touch each other and to not take things out of others hands.
I am unsure of the age group so my answers may not be great depending on the age, but I’m assuming they are toddlers.
Another solution is buying more toys? Although that could get pricey depending on how many kids there are. Maybe you could also have “shifts” where one group of kids goes outside and another goes in. When the group that was outside comes in, you switch. (If that makes sense.)
The kids inside could read, or sing, etc.
