The secretary . . . . . . . the society’s funds, . . . . . . . . he was dismissed.

The correct answer is D. misappropriated, so.

The secretary misappropriated the society’s funds, so he was dismissed. This means that the secretary took the society’s money for his own use, and as a result, he was fired from his job.

The other options are incorrect because they do not make sense in the context of the sentence. For example, the secretary did not “misplaced” the society’s funds, meaning that he did not lose them. He also did not “rob” the society, meaning that he did not steal the money from them. And he did not “pirate” the society’s funds, meaning that he did not illegally copy them.

Therefore, the correct answer is D. misappropriated, so.
