Hello J.R.S.,
 
When you get a chance, please take a look at the chemistry question entered immediately below this one.  I think all of the answer choices are wrong.  What do you think?

Arturo,
Yes, I would agree. Certainly x-rays, as used in X-ray crystallography, would be an appropriate answer, as would possibly radio waves which I believe are part of the NMR approach to studying structure. But none of the choices presented Seem appropriate. Merry Xmas.
