Detailed explanation-1: -Lothar Meyer’s Atomic Volume Curve: Lothar Meyer a German chemist plotted a graph between atomic weight and atomic volume (i.e. atomic weight in solid state/density) and he find out that elements with similar properties occupied the similar positions on the graph.

Detailed explanation-2: -Julius Lother Meyer who studied atomic volumes and other physical properties of various elements found that if a graph a plotted between atomic volumes and atomic weights of various elements similar elements occupy similar positions on the curve.

Detailed explanation-3: -Lothar Meyer plotted a graph between the atomic volumes and atomic weights of the.

Detailed explanation-4: -Thus the work of Lothar Meyers has a significant contribution for determining the position of elements to be placed in the periodic table. Hence the correct option is B i.e. atomic masses.

Detailed explanation-5: -Julius Lothar Meyer was born in Heilbron, Germany, and became one of the most influential chemists of his era. He is remembered for his independent discovery of the periodic table, although his contributions tend to be over-shadowed by those of the more illustrious Russian, Dimitri Mendeleev in most accounts.
