AVegetable-based cleaning solvents
BPerchloroethylene (PERC) and other chlorinated solvents that are common dry cleaning chemicals and known carcinogens✓ Correct

Explanation

These contaminants sink through soil and groundwater, are persistent, and are classified as probable carcinogens. Former dry cleaning sites often require extensive and expensive remediation.
