Explanation:

This question tests correct Oxford comma usage in lists of three or more items. The Oxford comma is the comma before the final "and" in a list, which clarifies separation between items. Option A uses incorrect semicolons instead of commas for the list. Option B omits the necessary commas between list items and the Oxford comma, creating a run-on. Option C uses proper commas to separate each item, including the Oxford comma before "and" for clarity.

Answer:

C. George Washington, the first president, Claude Monet, a French artist, and Khufu, an Egyptian pharaoh
