Solution
The correct option is A Purkinje
Johann Evangelist Purkinje was a Czech anatomist and physiologist. He was one of the best known scientists of his time. In 1839, he coined the term 'protoplasm' for the fluid substance of a cell. Protoplasm is composed of a mixture of small molecules such as ions, amino acids, monosaccharides, water and macromolecules such as nucleic acids, proteins, lipids and polysaccharides.
