What is correct about reconsolidation in classical conditioning?

		After conditioning, if the CS is presented once, with no US, the animal /person will learn that the CS predicts no US.
		Following successful extinction, presenting the US alone in the context where the original conditioning was learned, causes the CR to reappear.
		Presenting the CS alone, elicits recurrence of the molecular processes underlying long term potentiation.
		Reconsolidation is a process that weakens the CS-US connection when the CS is presented once, with no US.
