Solution

The correct option is C Cell
The smallest viable unit which can grow, multiply and form a plant in tissue culture is the cell. A cell is a viable unit of the plant which is cultured in the tissue culture. When a cell is cultured, under the controlled condition on a nutrient culture medium of known composition by the technique of tissue culture, the genetic material of the cell starts dividing and increases the cell number by the formation of callus. The callus utilizes the auxin and cytokinin to form root and shoot respectively by the process of cell differentiation and specialization.
So, the correct answer is option C.
