Discussion
One can get information on chemical composition of samples using :
Answer: A
Chemical composition is obtained with EDAX.
In energy-dispersive X-ray analysis, the electron beam of an electron microscope knocks inner-shell electrons out of the atoms in the sample. As the atoms relax they emit X-rays whose energies are characteristic of each element, so the spectrum shows which elements are present and in what proportion.
TEM gives images and diffraction patterns of the internal structure, SEM alone images surface topography, and XRD gives crystal structure and phase. None of them on its own measures elemental composition.
