Which of the diethylbenzene isomers (ortho, meta, or para) corresponds to each set of 13c nmr spectral data? [a] 13c nmr signals: 16, 29, 125, 127.5, 128.4, and 144 ppm [b] 13c nmr signals: 16, 29, 128, and 141 ppm [c] 13c nmr signals: 15, 26, 126, 128, and 142 ppm

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.
