Increased production of corn ears in plants with mycorrhizae than in plants without mycorrhizae would support the claim that the presence of mycorrhizae improves plant growth and survival. The production of more corn ears is an indication of improved growth, and a higher survival rate would also indicate improved plant health. The other choices, smaller apple size in plants with mycorrhizae, increased need for fertilizer in plants with mycorrhizae, and increased mortality in plants with mycorrhizae would all contradict the claim that the presence of mycorrhizae improves plant growth and survival.
