Opponents of laws that require automobile drivers and passengers to wear seat belts argue that in a free society people have the right to take risks as long as the people do not harm others as a result of taking the risks. As a result, they conclude that it should be each person's decision whether or not to wear a seat belt.

Which of the following, if true, most seriously weakens the conclusion drawn above?

• AMany new cars are built with seat belts that automatically fasten when someone sits in the front seat.  
• BAutomobile insurance rates for all automobile owners are higher because of the need to pay for the increased injuries or deaths of people not wearing seat belts.  
• CPassengers in airplanes are required to wear seat belts during takeoffs and landings.  
• DThe rate of automobile fatalities in states that do not have mandatory seat-belt laws is greater than the rate of fatalities in states that do have such laws.  
• EIn automobile accidents, a greater number of passengers who do not wear seat belts are injured than are passengers who do wear seat belts.
