Science students began growing bean plants at the same time under four different conditions. Data about the heights of a random sample of plants grown under each condition were collected and are summarized below.
Heights of Plants
Mean

For which condition is the mean height likely closest to the actual height of most of the plants grown under that condition?
A low humidity
B high humidity
C low light
D infrared bulb

I need this answered immediately. Ill be putting up a photo as well. I’ll also be giving brainliest.
