Hint: Protoplasm constitutes of the cytoplasm, living nucleus, mitochondria and inorganic and organic substances of the cell. Protoplasm is the living part of the cell which contains various organelles of the cell. It is a colourless, transparent, jelly-like and viscous substance present within the cell. In 1835, the term protoplasm was proposed and is considered as a major substance which is responsible for various living processes in an organism.

Complete answer:
The protoplasm contains various components in the cell and cytoplasm is considered as the primary constituent of the cell which helps in maintaining shape and storing of essential substances in the cell. The second constituent of protoplasm is the nucleus which contains the genetic information of both the parents. Proteins, enzymes, fats and hormones are also the constituent of protoplasm and are present in suspended or dissolved form in the cell. The term protoplasm was coined by J. E. Purkinje and called as protoplasm as the living matter of the cell. Protoplasm is surrounded by plasma membranes of the cell. Protoplasm is also used to define cytoplasm along with the nucleus and is responsible for all living processes of the cells.

Hence, the correct option is A. Purkinje.

Rudolf Virchow is known for cell theory, cellular pathology and biogenesis. Robert Hooke is known for Hooke’s law and coined the term cell. Har Gobind Khorana is an Indian-American biochemist and was first to demonstrate the role of nucleotides in protein synthesis. J. E. Purkinje coined the term protoplasm and also protoplasm as living matter of the cell.
