Latest technique for purification, isolation and separation of organic compounds is?

The correct option is A Chromatography
The best and latest technique for isolation, purification, and separation of organic compounds is chromatography which is a method used by scientists for separating organic and inorganic compounds. Chromatography is based on differential migration. The solutes in a mobile phase go through a stationary phase. Solutes with a greater affinity for the mobile phase will spend more time in this phase than the solutes that prefer the stationary phase. As the solutes move through the stationary phase, they separate.
