In Tolman's Experiment Where One Group of Rats (Group B)

In Tolman's experiment where one group of rats (group B) was not reinforced revealed that, when both groups were subsequently reinforced:

A) group B solved the maze faster but with a much greater number of errors than group A
B) group B solved the maze as fast but with no errors
C) group B was slower and made more errors, as the experimenters expected
D) the two performed equivalently
