Copper deposit is defined as

• A. A type of gold alloy.
• B. A casket made from a core of copper metal to which copper ions are combined by an electrolytic process.
• C. A container made from cardboard.
• D. An interior lining element.

Answer: (B)

In funeral merchandising, a copper deposit casket is defined by its construction: a core shell made of copper with an outer surface finish created by electroplating copper ions onto that copper base. The electrolytic deposition process uses electric current to deposit copper from a solution onto the core, producing a copper-coated exterior. This distinguishes it from options that describe a gold alloy, a cardboard container, or an interior lining element. The term “deposit” here refers to the copper surface finish achieved through electroplating, not the material of the core or an unrelated component.
