Which word means not able to be erased or removed; memorable; permanent?

• A. Erasable
• B. Temporary
• C. Indellible
• D. Irreversible

Answer: (C)

This item is about choosing a word that expresses lasting permanence and a lasting memory. The word that fits both ideas—something that cannot be erased or removed and that can be memorable—is indelible. Indelible describes marks or memories that endure and cannot be wiped away. In everyday use, you might hear about an indelible stain or an indelible impression, meaning it leaves a lasting impact.

In the list, the exact intended spelling is indelible, which is the correct form. The version shown is a common misspelling, but the concept it represents is the one that matches the meaning described. Other options don’t convey both permanence and memorability: erasable means something can be erased, temporary means short-lived, and irreversible refers to what cannot be undone, not necessarily to lasting marks or memories. So the best fit is indelible.
