Which element is not listed among the essential nutrients in the material?

• A. Carbon
• B. Hydrogen
• C. Sodium
• D. Phosphorus

Answer: (C)

Essential nutrients are the elements that plants must have to complete their growth and life cycle. Among common plant nutrients, carbon, hydrogen, and phosphorus are required by nearly all plants and are typically listed as essential. Sodium, on the other hand, is not required by most plants to grow and reproduce. While some species can tolerate or even use small amounts of sodium, it is not universally necessary, and high levels can be harmful. Because the material’s list of essential nutrients excludes sodium, it’s the correct choice.
