The correct answer is ES
Explanation:
In English, most plural words end in -s or -es, which varies with the word. According to grammatical rules, singular words that end in s, sh, ch, x, z or ss can be made plural only by adding "es".
For example, "buses" is the plural form of "bus" ending in "s"; "bushes" is the plural of "bush" that ends in "sh"; "matches" is the plural of "match" that ends in "ch"; "foxes" is the plural of "fox" that ends in "x"; "buzzes" is the plural of "buzz" that ends in "z"; and "glasses" is the plural of "glass" that ends in "ss". Besides this, other words such as "fish" do not have changes, some imply changing "y" by "i" as "fly" and "flies" and most words only need an "s" to become plural such as kids, dogs, tables, etc.
