Answer:
D. informal
Step-by-step explanation:
Diction alludes to the words and expressions an individual uses in discourse or recorded as a hard copy. Casual word usage, at that point, is the casual, conversational language that we utilize each day.
Informal diction is used to address a familiar audience, for example, family or companions. Individual letters, messages, or records that have a conversational tone are altogether composed utilizing casual lingual authority. Books may likewise be written in this style to demonstrate's characters by utilizing slang, a certain dialect (a style of language from a specific region or group of people), or idioms (expressions whose figurative meanings are very different from their literal meanings).
