B is not the reason Nessy isn't accepted. It is a lack of clear undisputable evidence that is the problem
A The quotation says that there is shadows and movements in the lake, but no other signs of Nessy
Each of pollan's chapters focuses on one particular plant and pollan suggests that each plant satisfies a specific human desire. The potato satisfies our desire for control – even more so now that we control its genes.
Though people might consider potatoes ordinary everyday fare, history demonstrates how crucial this vegetable is to humankind. Prior to the invention of the potato, conditions were challenging; many people, particularly in northern European nations, suffered from starvation and famine.
Malnutrition and starvation were eradicated in the countries that embraced the potato, and as a result, they grew stronger and more powerful. It is even conceivable that the potato spread resulted in a transfer of power from southern European nations to northern ones.

Explanation:
Wetlands are the regions of land which are covered by water. The water can be fresh water, Saltish water or between these two. Low-lying areas of rivers or oceans, ponds, lakes and marshes, all fall under wetlands.
- Wetlands are extremely important for the life on earth because of immense number of services they provide to humans, wildlife and fish. They are more productive region than coral reefs and rain forests.
- They have an important role in protecting the shores from the strong action of waves that can cause floods. They also help in trapping sediments and thus lowering the losses due to soil erosion. This makes option A true.
- They provide habitat and food source to wide array of organisms such as fish and wildlife therefore option B is also true.
- They also help in the controlling of pollution because they clean or filter sediment from runoff water which ultimately helps in preventing mud clogging in water reservoirs such as lakes. Therefore, they have a cleansing or filtration action and this makes option C true.
Hence, D is the best option.
Hope it helps!
