During germination, peas sprout and grow. The data table shows the carbon dioxide produced during the germination period of peas under different conditions.ConditionRate of carbon dioxide produced (mL/min)Germinating peas, 10ºC0.01Germinating peas, 20ºC0.02What is the best conclusion?

A
The rate of cellular respiration in germinating peas is exactly one thousand times the rate of ATP production.
B
Germinating peas at 10ºC create carbon dioxide at a rate of 0.01 mL/min during ATP production.
C
Germinating peas at 20ºC have a higher rate of cellular respiration than germinating peas at 10ºC.
D
The rate of cellular respiration cannot be measured without knowing the rate of ATP production.
