Hint :The density of a matter is its mass per unit volume (more specifically, its volumetric mass density; also known as real mass). While the Latin letter D can also be used, the symbol for density is (the lowercase Greek letter rho ρ). Density is characterised mathematically as mass divided by volume.

Complete Step By Step Answer:
Density is characterised mathematically as mass divided by volume.
$\rho = \dfrac{m}{v}$
where the density is, the mass is m, and the volume is V. In certain contexts (for example, in the oil and gas industry in the United States), density is arbitrarily interpreted as its weight per unit volume, which is technically incorrect; this amount is more precisely known as specific weight.
Metals with relatively high densities, atomic weights, or atomic numbers are classified as heavy metals. Depending on the author and setting, the criteria used and whether metalloids are included differ. For example, in metallurgy, a heavy metal might be characterised by mass, while in physics, the defining criterion might be atomic number, and a chemist would be more concerned with chemical behaviour.
METALDENSITY (in g cm⁻³)

From the table we can conclude that Gold Is the heaviest metal among the following
Option B is correct.

Note :
Gold is a chemical element with the symbol Au (from Latin: aurum) and atomic number 79, which makes it one of the higher atomic number elements found in nature. It is a shiny, slightly reddish yellow, thick, smooth, malleable, and ductile metal in its purest form. Gold is a transition metal and a member of group 11 of the periodic table. It's one of the least volatile chemical elements, because it's stable at room temperature. In rocks, veins, and alluvial deposits, gold is often found in its free elemental (native) shape, as nuggets or grains.
