Select the most appropriate word to fill in the blank.

You are ______ responsible for this condition.

yourself

The most appropriate word to fill in the blank is yourself.

The word yourself is a reflexive pronoun that refers to the person speaking or writing. In this case, the sentence is saying that you are yourself responsible for this condition. This means that you are the only one who is responsible for this condition.

The other options are not correct.

• Themselves refers to more than one person. It cannot be used in this sentence because there is only one person being referred to.
• Itself refers to a thing or an animal. It cannot be used in this sentence because the person speaking or writing is not a thing or an animal.
• Myself is also a reflexive pronoun, but it is used when the person speaking or writing is the object of the sentence. In this sentence, the person speaking or writing is the subject of the sentence, so myself cannot be used.
