Answer:
I would believe that the correct answer is "C. diction"
Step-by-step explanation:
The definition of diction is: "the choice and use of words and phrases in speech or writing." Also, if you look at the word "dictionary," you see that its root word is "diction" and a dictionary is a book full of words. Style is the way that the object is written (as in its appearance, or how it is said) and does not just focus on the wording. Therefore, the answer is "Diction"
