Final answer:
Desdemona says the line in Othello expressing her admiration and love for Othello with intentional ambiguity.
Step-by-step explanation:
In William Shakespeare's play Othello, the line 'Now what exactly do those lines mean? We must assume that Shakespeare knew what he was doing with language, and yet these lines contain an obvious ambiguity.' is referring to the character Desdemona.
Desdemona says these lines, expressing her admiration and love for Othello. The ambiguity in her words reflects her desire for a man like Othello and her wish to have such adventures. Shakespeare intentionally wrote these lines with multiple interpretations.
Therefore, the correct answer to 'Who says this in Othello?' is Desdemona.
