Which of the following statements describes an inelastic demand? A. Megan did not buy too many hockey tickets even though their price dropped by 10 percent. B. People are buying HDTVs before the Super Bowl game begins. C. Arise in the tax rate has decreased imports of auto parts from China. D. Housing prices in London rose by 10 percent due to rock bottom interest rates.

The correct answer is C. A rise in the tax rate has decreased imports of auto parts from China.<br /><br />Inelastic demand refers to a situation where the quantity demanded of a good or service is relatively insensitive to changes in its price. In other words, even if the price of the good or service changes, the quantity demanded does not change significantly.<br /><br />In the given options, option C describes a situation where a rise in the tax rate has decreased imports of auto parts from China. This indicates that the demand for auto parts from China is inelastic, as the change in price (due to the tax increase) has led to a significant decrease in the quantity demanded.<br /><br />The other options do not describe inelastic demand. Option A describes a situation where the quantity demanded is not affected by a change in price, but it does not necessarily indicate inelastic demand. Option B describes a situation where people are buying HDTVs before the Super Bowl game begins, which is not related to inelastic demand. Option D describes a situation where housing prices in London rose due to low interest rates, which is also not related to inelastic demand.
