zero
If commodities X and Y are substitutes, their cross elasticity of demand will be positive. Substitutes are goods that can be used in place of each other. When the price of one substitute (e.g., X) increases, the demand for the other substitute (e.g., Y) tends to increase as consumers shift their preference. As a result, the cross elasticity of demand is positive.
