A. By sharing the groundskeeper's records that show there was no salting after 2:00.
Explanation:
In the given scenario, the claim is that the incident was caused by the unsalted ice ground by the Center. And the counterclaim by the Center is that it is not responsible for the injury because they did salt the ice as instructed.
So, the counterclaim for the Center's argument will be to provide records kept by the Center's groundskeeper which shows no salting was done after 2 pm. This will provide evidence of the claim that Mrs. Graves’s injury was an indirect fault of the Center.
