Pro-Tect Insurance Company has recently been paying out more on car-theft claims than it expected. Cars with special antitheft devices or alarm systems are much less likely to be stolen than are other cars. Consequently Pro-Teet, as part of an effort to reduce its annual payouts, will offer a discount to holders of car-theft policies if their cars have antitheft devices or alarm systems.

Which of the following, if true, provides the strongest indication that the plan is likely to achieve its goal?

• AThe decrease in the risk of car theft conferred by having a car alarm is greatest when only a few cars have such alarms.  
• BThe number of policyholders who have filed a claim in the past year is higher for Pro-Tect than for other insurance companies.  
• CIn one or two years, the discount that Pro-Tect is offering will amount to more than the cost of buying certain highly effective antitheft devices  
• DCurrently, Pro-Tect cannot legally raise the premiums it charges for a given amount of insurance against car theft.  
• EThe amount Pro-Tect has been paying out on car-theft claims has been greater for some models of car than for others.
