The answer to your question would be B. This is because GM stands for genetically modified, which means it is not natural. And that is why people prefer organic food if they can afford it, because they don't want to eat food that is not natural. Hope this helps! :D Feel free to ask more questions.
In urban areas, there are more people, therefore not a lot of farmland. (that eliminates C) If city buildings don't allow flood waters to recede, that could be dangerous in many ways. (So A is still a reasonable answer) If most cities are built in flood zones, there should be some form of shelter if houses aren't safe. Pollutants and diseases being carried in water are already dangerous, but easier to spread with rapid flood waters that are sweeping everywhere. So your best answer would be either A or B.
