In the region of Asia where snails commonly ingest trematode eggs, it is likely that free-swimming larvae released by snails in the water could have developed into a secondary form within the fish. Undercooking the fish would not have killed the larvae, resulting in a trematode infection for Rebecca. The other options are less likely as fecal contamination would not be the typical mode of transmission for trematodes, and trematode eggs do not typically develop into larvae within the flesh of fish.
