Given that demand and price remain unchanged an outward shift of the supply curve will lead to

An outward shift of the supply curve means that more of the good or service is being produced at every price level. Since demand and price remain unchanged, there will now be a surplus of the good or service, which means that the quantity supplied exceeds the quantity demanded. This excess supply is also known as a glut or oversupply, and it can lead to lower prices, lower profits for producers, and a buildup of unsold inventory. Therefore, the correct option is "excess supply".
