All of the given choices can be supported by the experiment. The improved growth rate of tomato plants suggests that the addition of arbuscular mycorrhizal fungi to the soil facilitated nutrient and water uptake by the plants, which could be explained by the penetration of fungal hyphae into root cells. Further, since mycorrhizal fungi are known to help plant roots absorb nutrients from the soil, it is possible that the soil used in the experiment was deficient in nitrogen or phosphorus, as indicated in choice B. Thus, all of the given choices are supported by the experiment.
