Three students test the effect of fertilizer on bean plant growth. Each student conducts one trial. They plant 10
bean seeds in each of three pots of soil with different
amounts of fertilizer. After 2 weeks, they measure the
heights of the plants in each pot. Then they find the
average height for each amount of fertilizer. The table
summarizes the results of the experiment.

Which statement describes a pattern shown in the data?
O A. The trend in the data for trial 2 shows that less fertilizer causes
more growth
O B. The data for the average heights of the plants in trials 1 and 2
contain errors.
O C. The trend in the data for trial 3 shows that plants grow taller if
given more fertilizer.
O D. The data from trial 3 are inconsistent with the data from trials 1
and 2
