The Graph Here Shows the Results of Growing One Strain

Multiple Choice

The graph here shows the results of growing one strain of a crop plant in soils with different nitrogen contents.
If a different strain of the same plant were grown in the same soils, you would predict that:

A) it would respond the same way to nitrogen supplementation because they are the same plant.
B) it would respond completely differently to nitrogen supplementation because they are different strains.
C) it could respond the same way or differently; different genotypes can, but may not always, respond differently to the same range of environments.
D) it could respond the same way or differently; the environment has too many variables to predict.
E) None of the answer options is correct.
