To determine the best summary of the first paragraph, we need to identify the main idea it conveys about Pluto’s classification.

This option encapsulates the general sentiment of Pluto’s status as a planet and acknowledges the shift in scientific consensus regarding its classification. It highlights both the past belief and the change over time, which is likely the focus of the paragraph.
