Both statements represent the classical Criteria of Essentiality established by Arnon and Stout (1939): Statement (I) is correct because an element is considered essential only if the plant cannot complete its vegetative and reproductive life cycle (setting viable seeds) in its complete absence. Statement (II) is correct because the requirement is non-replaceable and element-specific; the deficiency symptoms can only be corrected by providing that specific element. Option analysis: (A) Both Statement (I) and Statement (II) are correct is the correct answer. (B) Both are fundamental botanical principles. (C) Statement (II) is true. (D) Statement (I) is true.
