Well...think about it...you are looking for hidden costs of bottled water.
A. Bottles Water Sources - this will probably tell bring up where famous bottled water companies get their water, for example FIJI gets theirs from the Fiji islands and they add certain minerals and vitamins. I don't think this will get you close to your "hidden costs".
B. Costs Bottled Water - Although this search term doesn't make sense and does not have the word "hidden", it is probably the best choice. The search engine will probably bring up the regular costs of bottled water and then maybe somewhere in there you might find the hidden costs.
C. Risks Bottled Water - Although this one might seem correct, it is not. This will probably bring up the rumored risks of drinking bottled water. For example, drinking bottled Spring water might get mold inside of you, or the Dasani bottle had chemicals in its plastic that gives you a lesser life-span.
D. Water Use Costs - This one also might seem correct, but I think not. I think this will just bring up a bunch of water companies telling you how much it would cost for you to switch to their company and how much it is per gallon. It'll probably bring information on residencies and their water use or maybe states.
So B would be the best answer.
