Concept:Market supply increases when production becomes cheaper, enabling producers to sell more at the same price.
Explanation:Market supply refers to the total quantity producers are willing to offer at each price.
A rightward shift in supply occurs when the cost of production falls.
Subsidies on raw materials reduce the price producers pay for inputs.
Lower input costs lower the cost of producing each unit, making extra output profitable.
As a result, producers increase their output, causing market supply to rise.
Options A and C describe higher production costs, which reduce supply rather than increase it.
Option D raises the quantity supplied along the existing supply curve, but it does not increase overall market supply.
Thus, the only factor that directly increases market supply is a subsidy on raw materials.
Answer:B. subsidies on raw materials
