The correct answer is D. noun clause.
The clause <em>Maria was not going to show up </em>cannot be independent because it depends on the first part of the sentence. What did Tony realize? - That Maria was not going to show up.
Since it doesn't describe a noun or a verb, it cannot be an adjective/adverb clause either.
