Long ago the region was warmer, but the plants could not survive the change to cold.
Explanation: Tropical plant fossils in a now‑frozen area indicate that the local climate used to be much warmer, allowing those plants to live there. As the climate cooled, those plants could no longer survive in that location (they either died out or migrated). The other choices are unsupported or incorrect: you can’t conclude Earth never got cold, there’s no evidence polar bears ate them to extinction, and tropical plants aren’t adapted to grow in ice.
