To determine the average temperature change in the year 2000, I would need specific data or context to provide an accurate answer. However, if you're referencing a predefined set of options without additional information, it's impossible to ascertain the correct answer based solely on those figures.
If you have access to climate data or reports that specify the temperature change for that year, you can refer to those for verification. If this is a quiz or an educational question, it might be best to choose based on your knowledge or any context provided before.
