(D) According to Arnon and Stout $(1939)$,the criteria for essentiality of a mineral are:$1$. The plant must be unable to complete its life cycle in the absence of the element.$2$. The element must be specific and not replaceable by another element.$3$. The element must be directly involved in the metabolism of the plant.Since the element is essential for growth and development,it cannot be 'dispensable'. Therefore,being 'dispensable for growth' is not a criterion for essentiality.
