Answer 1

Answer:

D. Your mother's best silver tarnishes.

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.

Best regards.
