What is the Law of Supply?

The Law of Supply asserts that, all else being equal (ceteris paribus), an increase in the price of a good or service will lead to an increase in the quantity supplied. This relationship highlights how suppliers are generally motivated by potential profit. When prices rise, producers are incentivized to increase production because the higher prices can cover the costs of production and yield greater potential profits. This principle underlines the positive correlation between price and quantity supplied, which is a fundamental concept in microeconomics.

In the context of the other options, the first choice incorrectly suggests that prices do not affect supply, while the second choice misrepresents the relationship by indicating that an increase in price leads to a decrease in quantity supplied, which contradicts the Law of Supply. The fourth option incorrectly implies that supply is solely dependent on consumer demand, without recognizing the importance of prices and production costs for suppliers.
