Boron is a micro or trace element needed by plants in small quantity while others are needed in large quantity.so the answer is A
Boron is a trace element while others are major elements which are needed by plants in large quantities

note, all elements under first 20, require by plant in large quantity except Boron, while those above first 20, require in large quantity except cobalt and manganese

The ans is boron, because it's a micro element.Micro elements are elements that are required in small or minute quantity.
But Macro elements are required in a larger scales or quantities for different metabolic activities.eg potassium, Nitrogen ,etc.
