Answer 2

D. Your mother's best silver tarnishes.

Step-by-step explanation:

Hello,

In this case, the answer is: D. Your mother's best silver tarnishes, since tarnishing is a process carried out due to the effect of an external condition (aging, wearing out and others), not a property. Properties are actually descripted on options A, B and C as they describe the material in terms of its nature.

Best regards.
