Concept:Market supply increases when the supply curve shifts to the right due to a change in a supply determinant, not due to a change in the commodity’s own price.
Explanation:An increase in market supply means that at every price, producers are willing to supply a larger quantity.
This shift is caused by:
• An improvement in innovation and technology, which lowers production costs and increases output.
• A reduction in the cost of raw materials, making production cheaper and more profitable.
• A favourable weather condition, which boosts agricultural output and raises supply.
However, an increase in the price of the commodity does not shift the supply curve.
Instead, it causes an upward movement along the same supply curve, showing a rise in quantity supplied, not market supply.
Therefore, the factor that does not cause an increase in market supply is an increase in the price of the commodity.
Answer:B. An increase in the price of the commodity
