As proposed by Dalton in his atomic theory, each element had a unique symbol. Phosphorus was represented by a circle with three lines radiating outwards from the center to the circumference.

Dalton’s symbols were pictorial representations of elements and compounds, unlike the modern alphabetical symbols.

Other examples of Dalton’s symbols include a simple circle for Oxygen, a circle with a dot in the center for Hydrogen, and a circle with vertical and horizontal lines crossing for Sulphur (often shown as + inside circle or vertical/horizontal lines). Option A represents the modern symbol for Phosphorus inside a circle, which was not Dalton’s representation.
