O a) Radio Analytical method
O b) Miscellaneous method
O c) Thermal method
O d) Electro analytical method​

Answer 1

Radio Analytical method includes all the  techniques such as ion-exchange  chromatography, solvent extraction which  are mainly used as separation methods.

Explanation:

• In the Radio Analytical method, the radioactivity of different elements is studied.
• This method is helpful in studying the phenomenon of radioactivity in naturally occurring and artificial radioactive elements.
• The classical methods that are used in radioactivity are qualitative and quantitative analysis, spectroscopy, mass spectroscopy, separation.
• These separation techniques are used for separating the ions of radioactive elements.
