What is cross-price elasticity of demand?

The percentage change in the price of one good divided by the percentage change in the price of another good; measures the relative price movements between goods.

The percentage change in quantity demanded of one good divided by the percentage change in the price of a different good; measures how demand for one good responds to price changes of another.

The percentage change in quantity demanded of a good divided by the percentage change in its own price; measures demand responsiveness to its own price.

The percentage change in quantity demanded of a good divided by the percentage change in consumers' income; measures how demand responds to income changes.
