If elasticity of demand is 10,a 1% increase in price will lower quantity demanded by

A) .1%.
B) 1%.
C) 10%.
D) 100%.

The elasticity of demand measures the responsiveness of the quantity demanded to a change in price. An elasticity of 10 means that a 1% increase in price will result in a 10% decrease in quantity demanded, and vice versa. Therefore, the correct answer is C, as a 1% increase in price will lower quantity demanded by 10%.
