Answer 1

The correct option is A potassium , nitrogen, and phosphorus

The most important elements that plants need, without which they won't thrive, are the three macronutrients: potassium, nitrogen, and phosphorus. Because they are basic building blocks of every plant are ATP, cell membranes and amino acids. Nitrogen is an element in every amino acid; ATP, which is the primary source of energy for all cells, contains phosphorus. Potassium is essential to a plant's ability to metabolize. This element also comprises up to two percent of a plant's weight.

So, the correct answer is 'Potassium, nitrogen, and phosphorus'.
