What are the 'determinants of supply'?

The correct choice identifies the 'determinants of supply' as conditions that can change the supply of goods or services. These determinants include various factors that influence how much of a product producers are willing and able to sell at different prices. Key determinants of supply typically include the production costs, technology, number of suppliers, and the prices of related goods.

When any of these factors change, they can directly affect the quantity of goods supplied. For example, if the cost of raw materials decreases, suppliers may be able to produce more at a lower cost, thereby increasing supply. Similarly, advancements in technology can enhance production efficiency, allowing for an increase in supply.

Understanding these determinants is crucial for analyzing market changes and predicting how shifts in supply can impact prices and availability of goods in an economy.
