Answer: D. Change Decade’s to Decades
Explanation:
When the suffix 's is used on a noun, it denotes an ownership interest in the word that comes after the noun by the noun. In other words, if the suffix is used with a noun, it shows that the noun either owns or is connected to the next word. For instance, this is Brainly's website. This means that Brainly owns this website.
Using the suffix on the word Decade to describe it in plural form is therefore wrong. The correct way to denote the plural form of Decade would be to add an "s" so that it becomes Decades.
