The statement that is most likely to explain the change in the population proportion of green toads from 20% to 50% is:

The environment changed such that green toads can blend into their surroundings better.

This explanation suggests that the change in the environment favored the green toads, allowing them to avoid predation more effectively than the brown toads, hence leading to an increase in their population proportion over time.
