Bi-b, ii-c, iii-a, iv-d

Ci-d, ii-b, iii-c, iv-a

Di-a, ii-d, iii-b, iv-c

Correct answer: (A) i-c, ii-a, iii-d, iv-b

Explanation

The F-list covers hazardous wastes from non specific sources common to many industries.

The K-list covers hazardous wastes tied to specific industrial processes.

The P-list holds acutely hazardous discarded chemicals with the low threshold of one kilogram per month.

The U-list holds toxic discarded chemicals with the higher threshold of twenty five kilograms per month.

The pairing turns on whether the source is broad or specific and on the discard threshold.

These lists come from the United States hazardous waste classification system.
