Correct Option(3) Potassium
Explanation:
Among the given elements, potassium (K+) is responsible for maintaining turgor pressure in cell because it regulates the proton pumps involved in opening and closing of stomata. Magnesium (Mg2+) is a constituent of chlorophyll pigment which helps in photosynthesis in green plants. Calcium (Ca2+) provides selective permeability to the cell membrane. All of these, i.e. K+, Ca2+, and Mg2+ are essential elements.
Sodium (Na+) is involved in membrane permeability. It is a non-essential element.
