Correct Answer
Permeable
Explanation
Rule: An antonym must represent the exact opposite meaning of the provided word.
Formula: Impervious (Not allowing fluid/passage through)} ←→ Antonym (Allowing passage through)
Application: "Impervious" means unable to be affected, penetrated, or passed through. Therefore, "Permeable" (which means allowing liquids or gases to pass through) is its direct antonym. Options like Impregnable and Impassive act closer to synonyms or unrelated descriptors.
