B Correct answer
Explanation

Phosphorus is important in plant bioenergetics.It is a component of the complex nucleic acid structure of plants, which regulates protein synthesis. As a component of ATP, phosphorus is needed for the conversion of light energy to chemical energy (ATP) during photosynthesis. It is a primary macronutrient of the plants
