Select the grammatically correct word to finish the homeowner's proud (but misplaced) boast.

"I didn't need to hire a professional plumber! I fixed the leaking sink ____," Arthur proclaimed, right before the pipe burst and flooded his kitchen.

In this sentence, myself acts as an intensive (or emphatic) pronoun. It isn't strictly necessary for the sentence to make sense, but it is used to emphasize that the subject ("I") performed the action entirely alone, without any outside help.
