(C) The criteria for essentiality of an element were proposed by Arnon and Stout $(1939)$.According to these criteria,an element is considered essential if it is required for the plant to complete its life cycle and if it is involved in the metabolic processes of the plant.Nitrogen,Sulphur,and Potassium are macronutrients essential for the growth and development of all higher plants.Sodium $(Na)$ is considered a beneficial element rather than an essential one for most higher plants,although it is required by some specific plants like $C_4$ plants and blue-green algae for certain metabolic functions.Therefore,Sodium is not classified as an essential element for the growth of all plants.
