Answer:
B) phytoremediation.
Step-by-step explanation:
Phytoremediation is a method of cleaning up contaminated soil or water using plants. In this method, plants that are known to accumulate certain contaminants are grown on the contaminated soil or water. The plants absorb the contaminants through their roots and leaves, and can then be disposed of as toxic waste, removing the contaminants from the environment. In the case described in the question, the plants are being used to clean up the nonbiodegradable organic compounds in the abandoned field. Therefore, the correct answer is B) phytoremediation.
