Solution

The correct option is B Phosphorus
Phosphorous is an essential macronutrient. It is required for biosynthesis of nucleotides, nucleic acids, phospholipids etc. Its deficiency leads to poor growth, dull green leaves, red anthocyanin spots, premature leaf fall, premature fall of flower buds and delayed seed germination.
