C. no, because he used different soils. The answer is C. Joe used different soils. Each soil has its own properties which could greatly affect the growth of a plant.For instance, sandy soil has big particles hence drains water fast, it is therefore not the best soil for growing a plant compared to loam soil which has small particles which is the best soil for growing plants. Assuming that he used sand and loam soil, the plant will grow differently hence he will not get accurate results of his experiment.
