The correct option is A Boron
Boron is a micronutrient that is required for pollen germination, root modulation, cell elongation, and carbohydrate translocation.
Calcium is required for the organization of the mitotic spindle, metabolism, meristematic activity, secondary message for some hormonal signals, etc.
Chlorine is required for cell division, production of fruits, etc.
Potassium maintains the cell turgidity, cation-anion balance, respiration, protein synthesis, opening and closing of stomata, etc.
