Socrates' style in The Apology affects the text's readability. Option C is correct.
Plato's The Apology is an account of the speech Socrates delivers at the trial in which he is charged with not recognizing the gods worshiped by the state, inventing new deities, and corrupting the youth of Athens. Socrates' speech, however, is an "apology" in our modern understanding of the word.
Socrates speaks in a very plain, conversational manner.
