Which phrase indicates that a remedy has no effect?

• A. Remedy has No effect
• B. Remedy is Antidote
• C. No change
• D. Symptoms relapses

Answer: (A)

Recognizing when a remedy did not produce any observable action is about identifying a lack of response in the patient. The clearest way to express that is a direct statement that the remedy has no effect—it's explicit and unambiguous about zero action. Other phrases point to different phenomena: calling a remedy an antidote signals it is counteracting something, which means it did act; noting that symptoms relapse shows there was an effect that later waned, not a complete absence of effect; and saying there is no change can describe overall lack of improvement but doesn’t explicitly attribute that absence to the remedy’s action. So the phrase that most clearly indicates no effect is the direct claim that the remedy has no effect.
