Option D sets the initial message in the text area using setText() and adds a newline character to move to the next line. Then, the cost is added to the text area using the append() method. This results in the intended message "Your cost is:" followed by the actual cost on the next line. Option B is not correct because there is no addText() method for JTextArea. Option A is incorrect because the cost needs to be converted to a String before appending to the text area. Option C is incorrect because the cost and message should be concatenated with a "+" symbol.
