Since the user has not specified a particular word to convert into its plural form, and the image itself is an educational poster outlining the rules rather than a specific problem to solve, I will demonstrate how to use these rules by converting the word "box" into its plural form.
Here is the step-by-step reasoning:
1.
Identify the word: The word is "box".
2.
Look at the end of the word: The word ends with the letter "x".
3.
Check the rules:
* Rule 1 (add -s) is for most words.
* Rule 2 (drop y, add -ies) is for words ending in 'y'.
* Rule 3 says: "ends in ch, s, sh, x, or z - add -es".
* Rule 4 is for words ending in f or fe.
4.
Apply the correct rule: Since "box" ends in "x", we follow the third rule. We need to add "-es" to the end of the word.
5.
Calculate the final word: box + es = boxes.
Final Answer:
boxes
