CBP's answer: A. A: The importer of the detained shipment must bring the shipment into compliance with Toxic Substances Control Act or export the shipment from the customs territory of the United States within 90 days after notice of detention or 30 days of demand for redelivery, whichever comes first.

For a detained TSCA covered commodity, the importer must bring the shipment into compliance or export it within 90 days after notice of detention or 30 days of demand for redelivery, whichever comes first (12.124(a)). That is A. The 120 and 60 day figures in C are wrong, and the written-documentation choices are not what this paragraph requires.
