On which planet would you find a year lasting 225 Earth days?

A year lasting 225 Earth days corresponds to the orbital period of Venus around the Sun. Venus takes approximately 225 Earth days to complete one full orbit, making it one of the planets with a relatively long year in comparison to its day length. Interestingly, while Venus experiences this longer year, its rotation on its axis is quite slow, resulting in a day that lasts about 243 Earth days, leading to an unusual scenario where a day on Venus is longer than its year.

In comparison, Mars, Earth, and Mercury have shorter orbital periods. Mars takes roughly 687 Earth days to complete a year, Earth has a year of 365 days, and Mercury takes only about 88 Earth days to orbit the Sun, which reflects their proximity to the Sun and the physical characteristics of their orbits. Thus, pointing out that the choice reflecting a 225-day year aligns perfectly with Venus's orbital characteristics solidifies it as the correct answer.
