Answer:
I believe the answer to be letter B) It is essential for clear and understandable written communication.
Explanation:
As Martha Kolln says in the book Rhetorical Grammar (1999), "Diction will be effective only when the words you choose are appropriate for the audience and purpose, when they convey your message accurately and comfortably."
When we look up the word diction, we find several meanings, all interconnected, but with slight differences. In general, it can be said that diction refers to the choice of words an author makes. Such choice has a certain audience in mind and the purpose of making the piece of writing completely understandable. It is not only about choosing the correct words, but about choosing the correct words for that specific audience, to convey that specific message.
If I'm addressing an everyday issue while writing to an everyday audience, there will be no reason to choose a formal academic style with technical words. If my audience is formed by people who are not specialists in a certain area, using technical words of that area will only make them bored or uncomfortable. Thus, diction is essential to make my writing accessible and understandable to my audience.
Note: When it comes to literature, prose or poetry, diction refers to the choice of words that confers a certain style to the piece. It helps the speaker convey feelings, emotion, sensations, creating the mood.
