Which word is spelled correctly according to Canadian English standards?

The correct choice is "Flavour," which adheres to Canadian English spelling conventions. In Canadian English, words that include a "u" in the second syllable, such as "colour," "flavour," and "favour," retain the British influence that incorporates the letter "u." This is a distinguishing trait compared to American English, which typically drops the "u" in these words.

The other options present alternatives that follow American English spelling. "Color" is the American variant, lacking the "u." "Travelled," while it might seem correct, actually follows British spelling with the double "l" but varies across contexts. However, "travelled" retains both the British and Canadian forms. "Favorite" also conforms to the American spelling, where the "u" is omitted, contrasting with the Canadian preference of "favourite."

Understanding these nuances is essential for grasping the differences between Canadian English and other variants, which can be particularly useful in educational and professional settings.
