Answer:
The correct answer is letter C. In spite of the fact I am on a diet, I have not lost any weight.
Step-by-step explanation:
A wordy language is such a language that have an exagerate use about some idea you would like to show, but you could transmit it with less words and not adding more words on the sentences. In the case of the following sentece: In spite of the fact that I am on a diet, I have not lost any weight, it is not necessary use the word "fact" because for by itself the expression expresses the main idea of the sentence. If you see the letter B. "Even though I am on a diet, I have not lost any weight", you can see the same idea, the same conjuction as "In spite of" but without the wordy language like "The Fact".
