I do not know if this is what you are looking for due to lack of specific details but i would conclude that Object B will get do the destination after Object A because Object A is lighter.?
Does this help?
Answer:B
Explanation: Using Chemicals or pesticides would make it so that the invasive species would adapt to the new chemical, making it even harder to get rid of them. It’s helpful for the time being, however it doesn’t help for the long term. Introducing a predator, is like using 1 new species, to get rid of another new species. If you get rid of the invasive species, you still have to deal with the new predator. Hunting competitions can help, however they would only really work for animals. I don’t think hunting for plants would arouse much interest. Preventing them from invading a new environment would make it so that the damage will never be done...
