A sentence that contains wordy language is the one that uses more words than necessary, and it is frequently redundant. The unnecessary words repeat the same idea over and over again. These words can be erased without having the sentence lose its meaning. In sentence B, the word "yet" is redundant, and sentence C can be reduced to "Charlotte's bike was stolen while they where shopping; it conveys the same idea and avoids wordiness. Therefore, the correct answer is A: Both sentences contain wordy language.
