Explanation:

A rate describes how a quantity changes over time. The option "Some kinds grow four feet a day" specifies the growth amount (four feet) per unit time (a day), which directly shows the growth rate of bamboo. Other options do not provide such a quantitative time-related measurement.

Answer:

"Some kinds grow four feet a day."
