Auxiliary attachments, such as hooks and elastics, are typically found on braces on the brackets and bands. The wires, option A, are typically used for adjusting the position of teeth, rather than attaching auxiliary components. The dental chair, option C, would not have any attachments to the braces as it is simply used for positioning the patient during procedures. The patient's dental record, option D, would have information about the patient's treatment and progress, but would not physically contain any attachments to the braces. Therefore, option B is the most accurate answer.
