Choose the option that best completes the gap(s).

Of the three girls, Uka is the _____.

Answer Details

The correct answer is "naughtiest". This is because the sentence is comparing Uka's level of naughtiness to the other two girls, and identifying her as the one with the highest level of naughtiness. "Naughtiest" is the superlative form of "naughty", meaning the most naughty or mischievous.
