In a rural region of India, scientists collected data of different pesticide residue levels from closely located farming plots. Some of these plots usedintegrated pest management biopesticides, while others used chemical pesticides to control pests. The data below show levels of four pesticide residuesfound in tomato and cucumber crops in the two treatment plots. Crop TreatmentResidue Level ()

Monocrotophos Chlorpyrifos Endosulfan Cypermethrin
Tomato Integrated pest management
Tomato Pesticides
Cucumber Integrated pest management
Cucumber Pesticides

Which of the following statements is best supported by the data in the table?

a. Crops grown using integrated pest management have higher levels of all pesticides in cucumbers but do not have higher levels in tomatoes.
b. Integrated pest management resulted in substantially higher levels of all four pesticides in tomatoes.
c. The greatest effect of integrated pest management was seen in lower levels of endosulfan in both tomatoes and cucumbers.
d. Crops grown using integrated pest management had lower levels of monocrotophos measured in both tomatoes and cucumbers.
