Scientists conducted an experiment in which belladonna plants were grown in containers with their roots immersed in a pond contaminated with volatile organic compounds (VOCs). The plants kept growing, and in the process, they absorbed the VOCs. Within three weeks, 80 percent of the VOCs were removed from the water, a quantity comparable to what can be accomplished with more expensive water treatment methods. Scientists therefore propose using belladonna plants for decontamination wherever there are VOC-contaminated ponds.
Which of the following, if true, points to a limitation on the applicability of the proposed method of decontamination?
A. Some plants other than belladonna can also remove VOCs from water.
B. The water in many ponds contaminated with VOCs is so cold that it would soon kill belladonna plants whose roots were submerged in it.
C. Belladonna plants that grow with their roots submerged in water grow less well than those growing under optimal conditions on dry land.
D. Only species of belladonna with large leaves can have their roots submerged in water and still keep growing.
E. In ponds in which the circulation of the water is artificially increased, belladonna plants absorb VOCs far faster than they do in other ponds.

A.Some plants other than belladonna can also remove VOCs from water. not the question
B.The water in many ponds contaminated with VOCs is so cold that it would soon kill belladonna plants whose roots were submerged in it. looks fine
C.Belladonna plants that grow with their roots submerged in water grow less well than those growing under optimal conditions on dry land. question is not how fast they grow
D.Only species of belladonna with large leaves can have their roots submerged in water and still keep growing. not talking about the frequency of large leaves
E.In ponds in which the circulation of the water is artificially increased, belladonna plants absorb VOCs far faster than they do in other ponds. they might absorb faster, but this statement doesnt indicate any limitations

A.Some plants other than belladonna can also remove VOCs from water.
- Irrelevant
B.The water in many ponds contaminated with VOCs is so cold that it would soon kill belladonna plants whose roots were submerged in it.
- talks about other ponds and reason why belladonna cannot grow over there seems valid. Hold.
C.Belladonna plants that grow with their roots submerged in water grow less well than those growing under optimal conditions on dry land.
- Irrelevant
D.Only species of belladonna with large leaves can have their roots submerged in water and still keep growing.
-Irrelevant, the argument doesn't mention planting belladonna with small leaves. OOS
E.In ponds in which the circulation of the water is artificially increased, belladonna plants absorb VOCs far faster than they do in other ponds. - irrelevant
Thus, B is the best option.
