What does "bullion" refer to?

Bullion refers specifically to precious metals, particularly gold and silver, that have been refined and cast into bars or ingots. This term is often used in the context of investment, where individuals or institutions buy and sell these metals in their solid form for financial purposes. The definition encompasses not only the physical materials but also their intrinsic value in the global market.

In contrast, the other options relate to completely different concepts. A heavy club references a type of weapon or tool, an eating disorder pertains to a serious mental health condition related to food and body image, and a type of soup does not connect with the definition of bullion in any way. The term "bullion" is firmly rooted in finance and commodities, marking it distinct from the meanings of the other choices.
