Answer:
a) decrease in equilibrium price and an increase in equilibrium quantity.
Explanation:
As the input cost decreases for the companies the the supply of the goods increases hence the supply curve shifts rightwards.In the curve at the new equilibrium point the equilibrium price decreases and the equilibrium quantity increases.
Think it like if cost of creating anything is decreased for a company then the company will create more products .So there will be more products in the market.So to clear the products in the market the price will be reduced and the quantity of the product is more than before.
