Final answer:
The retentionist response to the Mistake Argument that refers to the acceptability of raising speed limits on freeways is to oppose the Mistake Argument.
Step-by-step explanation:
The retentionist response to the Mistake Argument that refers to the acceptability of raising speed limits on freeways is D) Opposing the Mistake Argument. The Mistake Argument suggests that if the death penalty is acceptable, then raising speed limits on freeways should also be acceptable, since both can potentially result in innocent deaths. A retentionist response to this argument would oppose it and argue against the correlation between the death penalty and raising speed limits. They might argue that the death penalty serves as a necessary deterrent and that it should be evaluated on its own merits and not compared to other unrelated issues.
