Choose the grammatically incorrect omitted part of the sentence from the following list:

told by idiot

The correct answer is Option (2) - told by idiot

The full phrase should read: "It is a tale told by an idiot, full of sound and fury, signifying nothing." This is a famous line from William Shakespeare's play Macbeth. The article "an" is necessary before "idiot" because it precedes a vowel sound.
