Concept:The word "Wilt" means to lose freshness, droop, or become weak. Its opposite is a word that means to restore strength or bring back to life.Explanation:The word "Wilt" (मुरझाना) is used when a plant or person becomes limp or loses energy. For example, flowers wilt in extreme heat without water."Revive" (पुनर्जीवित करना) means to bring back to a healthy, active state. For example, giving water to a wilted plant helps it revive and become fresh again.Since "Revive" restores what "Wilt" takes away, they are direct opposites.The other options — Cruel, Merciless, and Strict — do not relate to the state of becoming limp or losing vitality. They describe harsh or severe behavior, not a physical or energetic condition.Therefore, the correct antonym of "Wilt" is "Revive".Answer:C. Revive
