The correct answer is letter C
Supply and demand are the two forces that guarantee the functioning of a market, determining prices and the quantity of products offered. The term offer refers to the quantity available of a product, that is, the quantity that companies want or can sell.
Supply is also basically determined by some important factors such as:
1. Product price
2. Competitive product prices (complementary too)
3. Price of factors or production resources (cost of inputs)
4. Available technology
5. Number of producers competitors operating in the market
6. Producers' expectations about future prices
7. Availability of credit for financing and working capital
8. Government policy (taxes and subsidies)
9. Climatic conditions (agriculture)
The determinants of joint supply define how much of a specific good the producers are willing to sell in a given period of time.
