In Regard to Atomic Absorption (AA)spectrophotometry,which One of the Following

In regard to atomic absorption (AA) spectrophotometry,which one of the following statements is correct?

A) The technique combines laser-induced fluorometry and particle light scattering analysis to differentiate molecules,cells,or particles by size and shape.
B) The technique measures concentration through the detection of absorbance of electromagnetic radiation by atoms of elements instead of molecules.
C) Oxidation of an organic compound such as luminol induces an excited state,and light is emitted when the electron returns to the ground state.
D) The amount of light scattered at right angles to the incident light is directly proportional to the concentration of the analyte of interest.
