10 since she was four so she dances beautifully. A is dancing has been danced was danced has been dancing

The correct answer is **A. has been dancing**.<br /><br />The sentence should read: "Susan has been dancing since she was four, so she dances beautifully."<br /><br />The present perfect continuous tense ("has been dancing") is used to describe an action that started in the past and continues to the present. The phrase "since she was four" indicates the duration of the action.<br />
