To answer this question, we need to understand the meanings of the given words and choose the option that best fits the meaning of the sentence.
Option A) exonerated - This option means to absolve someone from blame or wrongdoing. However, in the sentence, the jury is not absolving the mayor of wrongdoing but rather finding him guilty.
Option B) expatriated - This option means to banish or deport someone from their own country. This does not fit the meaning of the sentence as the jury is not banishing or deporting the mayor.
Option C) augmented - This option means to increase or make something greater. This does not fit the meaning of the sentence as the jury is not increasing or making anything greater.
Option D) subjugated - This option means to bring someone under control or domination. This does not fit the meaning of the sentence as the jury is not bringing the mayor under control or domination.
Therefore, the correct answer is A) exonerated. This option is incorrect because the jury is not exonerating the mayor of wrongdoing, but rather finding him guilty.
