Answer 1

Right choice is (b) To find the elemental composition of living tissues

For explanation I would say: Elemental analysis gives the elemental composition of living tissues in the form of hydrogen, oxygen, chlorine, carbon, etc. while analysis for compounds gives an idea of the kind of organic and inorganic constituents present in living tissues.
