(c) Stereo Microscope(iii) Element profile
(d) X-Ray Diffraction(iv) Molecular Structure

Answer: (3) (iii), (iv), (i), (ii)

-> Neutron activation analysis (NAA) is the nuclear process that relies on the measurement of gamma rays emitted from a sample. These emitted rays give a concentration and element profile of the sample.
-> Mass spectrophotometer is used for depicting the molecular structure of the compound.
-> Stereo Microscope produces a 3d view of the specimen.
