A gardener wanted to know how soil temperature affects the sprouting of a variety of bean. She planted 100 seeds at each of five constant soil temperatures and, after ten days, recorded the percentage of seeds at each temperature that had germinated. Her results are shown in the table.

Germination of bean seeds after ten days, by soil temperature

Soil temperature (°A)	Seeds germinated (%)
10	32
15	60
20	79
25	88
30	60

The gardener concluded that germination improved as the soil warmed from 10 °C to 25 °C but that raising the temperature beyond 25 °C brought no further benefit. Which choice most effectively uses data from the table to support the gardener's conclusion?

AGermination increased steadily as the soil warmed, reaching its maximum of 88% at 30 °C.

BAt 25 °C, 88% of the planted seeds germinated within ten days.

CGermination climbed from 32% at 10 °C to 88% at 25 °C and then fell to 60% at 30 °C.

DGermination was the same at 15 °C and 30 °C, showing that soil temperature had little effect on the seeds.
