The correct option is C Grew
The term parenchyma was coined by English botanist and plant physiologist Nehemiah Grew. Grew stated that every plant organ had two parts, a ligneous (woody) and a pithy part composed of undifferentiated cells with air spaces between them. Parenchyma is a tissue typically composed of living cells that are thin-walled, unspecialized in structure, and therefore adaptable, with differentiation, to various functions. Thus, option C is correct.
