What action did Twilly take after witnessing littering by a driver?

The option indicating that Twilly followed the man 300 miles aligns with an extreme response to witnessing littering, suggesting a chase in pursuit of the perpetrator. This choice emphasizes Twilly's intense reaction and commitment to confronting the issue of littering. Following someone for such a distance shows not only a determination to hold the driver accountable but also highlights the lengths to which Twilly is willing to go to address the problem.

In this context, it reflects a character trait of being proactive and passionate, albeit in a rather exaggerated manner. This kind of action signifies a deep-seated concern for environmental issues and a desire to take personal responsibility in addressing them, showcasing a narrative of vigilance regarding public cleanliness and accountability. The other options, while potentially plausible responses to witnessing littering, do not convey the same level of commitment or dramatic pursuit that following the driver for 300 miles does.
