Which term describes a rise in supply at any given price, shifting the supply curve to the right?

• A. Increase in Supply
• B. Decrease in Supply
• C. Change in Supply
• D. Extension in Supply

Answer: (A)

A rise in supply at any given price means the whole supply curve shifts to the right. This happens when non-price factors make production cheaper or easier (like better technology or lower costs), so producers are willing to offer more at every price. Graphically, that’s a rightward shift of the supply curve, not a movement along it. That’s why the precise term is an increase in supply. It’s different from an extension in supply, which would be a movement along the same curve caused by a price increase, and from a decrease in supply, which would shift the curve to the left.
