Inflation leads to an increase in the general price level, including the costs of raw materials, labor, and other inputs needed for production. As these costs rise, producers may find it less profitable to supply the same quantity of goods at previous prices.
Thus, inflation typically reduces supply in the market by increasing production costs. Option 1 is incorrect because inflation does not lower production costs, and Option 3 is incorrect as inflation does affect supply by raising costs.
Option 4 is also incorrect because inflation typically leads to a decrease in supply, not an increase due to higher demand.
