Which of the following describes an "indelible" stain?

An "indelible" stain is characterized by its permanence; it cannot be easily eradicated and remains resilient over time. The term "indelible" denotes that something is enduring and cannot be wiped clean or forgotten, which is often used metaphorically to describe impressions or marks that leave a lasting effect. Therefore, selecting the option that states the stain lasts permanently aligns perfectly with the definition of "indelible." Understanding this concept is crucial, as it helps clarify the distinction between temporary and permanent effects in various contexts, whether discussing stains, memories, or influences.
