The correct answer is B.
In a excess supply situation like the one described, the quantity available of a certain product is larger than the amount that consumers demand of it. The market will tend to move back towards the equilibrium, to an scenario in which demand and supply and therefore, the desires of consumers and producers, meet again.
When the price goes down, according to the law of demand (this law states that if the prices is modified, the quantity demanded will change in the opposite direction), more people will be willing to purchase candy at a relatively lower price and more people will be able to afford it. Therefore, quantity demanded increses. The prices will continue on the same downward tendency until demand and supply meet.
