What is a suffix?A suffix is a group of letters that we place at the end of a word in order to change its meaning, creating a new word.Some words will not change their spelling at all when a suffix is added. Other words will follow certain spelling rules.We can notice that most of the words in the list given in the question either don't change their spelling, or change it in a way that does not affect pronunciation.For example, "ally" becomes "alliance", but the sound represented by "y" and "i" is the same. We also drop the -e in "grieve" to form "grievance," but it was silent in the original word.The only word that has a change in spelling to reflect a change in pronunciation is "remembrance." We drop the -e that comes before the -r in "remember" to show that the pronunciation is different when we add the suffix -ance.

With the information above in mind, we can select "remembrance" as the correct option.
