I'm not entirely sure about this one but If I had to guess I would choose D because by use of elimination you would know that Petroleum will run out, so it is not A. B isn't correct either because it is not evenly distributed throughout the country either. That leaves us with C and D. Hawaii does not have an abundant supply of oil like Petroleum. D makes the most sense because California and Texas are part of the top crude oil producing states in the country. Go with D.
