Answer:
c. be bad news for individual producers because when these factors shift the supply curve to the right it decreases total revenues.
Step-by-step explanation:
A good has an inelastic demand when quantity demanded doesn't change when price change.
When good news in an industry shifts the supply curve to the right, it means that supply has increased. When supply increases, there's an excess of supply over demand and prices fall. If price falls and quantity demanded doesn't change because demand is inelastic, total revenue would fall and this would be bad news for individual producers.
