The correct answer is D. satisfied.
The word “satisfied” means to be content or fulfilled. In the context of the sentence, the incident frustrated all his ambitions, meaning that it made him feel disappointed or discouraged. This is the opposite of being satisfied.
The word “satiated” means to have had enough of something, especially food or drink. In the context of the sentence, it would not make sense to say that the incident satiated all his ambitions. This is because the incident did not make him feel full or satisfied, but rather disappointed or discouraged.
The word “appeased” means to make someone less angry or upset. In the context of the sentence, it would not make sense to say that the incident appeased all his ambitions. This is because the incident did not make him feel less angry or upset, but rather disappointed or discouraged.
The word “cloyed” means to have become tired or bored of something. In the context of the sentence, it would not make sense to say that the incident cloyed all his ambitions. This is because the incident did not make him feel tired or bored of his ambitions, but rather disappointed or discouraged.
