The correct answer is B. Accusatory
Step-by-step explanation:
In writing the attitude of the author, narrator or characters towards some specific situation or subject is called tone, this attitude or tone can be identified by analyzing the election of words (diction), the use of descriptive details and in general terms the use of language of the author, narrator or character to refer to the subject or situation being described. Considering this, in the passage presented the character Teiresias refers to Creon by using the words "that's what you are doing when you claim my oracles are false" this means Teiresias is claiming Creon said his oracles are false and because of this Teiresias is accusing the other character of this. Therefore, the use of language suggests Teiresias' attitude toward Creon is mainly accusatory as he is blaming him for claiming Teiresias' oracles are false.
