B Correct answer
Explanation

Plastic is significantly lighter than gold. Gold is a very dense metal with a density of about 19.3 g/cm³, while most plastics have densities between 0.9-1.4 g/cm³. This means a given volume of gold would be about 15-20 times heavier than the same volume of plastic. Silver and copper are also metals denser than plastic.
