Two fertilizers

Jason is testing two fertilisers, Grow Well and Green Grow, on 50 tomato plants of the same variety planted in identical conditions. He applied Grow Well to 25 plants and Green Grow to the other 25. After four weeks, he measured the heights of the plants to the nearest inch:

Grow Well
Height (inches)	Number of plants
12–14	14
15–17	6
18–20	3
21–23	2

Green Grow
Height (inches)	Number of plants
12–14	4
15–17	3
18–20	6
21–23	12

A. The number of Green Grow plants over 18 inches is greater than the number of Grow Well plants over 18 inches.
B. All of the statements are false.
C. The number of Green Grow plants over 18 inches equals the number of Grow Well plants over 18 inches.
