C. positive and therefore these goods are substitutes.

Explanation:

Cross price elasticity is defined as a measure of the responsiveness of quantity demanded of a product to changes in price of another product. It is the percentage quantity change of a commodity when there is a percentage change in price of the other commodity.

Cross price elasticity = change in quantity of x/change in price of y

Cross price elasticity = 20/10 = 2

The cross price elasticity is positive this indicates that the goods are substitutes. Increase in demand for one results in decraese in demand of the other
