In the United States, certain states use the death penalty to punish

In the United States, certain states use the death penalty to punish those who commit murder. Other states do not use the death penalty in such cases, but sentence murderers to life in prison instead. In the states that do use the death penalty, the murder rate per 100,000 persons is higher than the rate in the states that do not use the death penalty. Thus, the death penalty only causes more murders and should be repealed in all states to reduce the murder rate.

Which of the following, if true, would most weaken the argument above?

A) Each state that has enacted the death penalty in murder cases over the last twenty years has seen a decline in the murder rate since the passage of those laws.
B) Many consider the death penalty to be morally wrong in all cases and oppose it regardless of the potential deterrent to murder.
C) In states that use the death penalty, some murderers are still only sentenced to life in prison.
D) The annual rate of non-violent crime is lower in states with the death penalty than it is in states without the death penalty.
E) In each state that uses the death penalty, over 60 percent of the state's citizens support the death penalty and believe that it is an effective deterrent to murder.
