Many Rats Were Tested for Their Ability to Learn a Maze.The

Many rats were tested for their ability to learn a maze.The average number of errors for a total of 14 trials was 64 per rat.The rats that made the fewest errors were bred to each other,and the offspring were tested in a similar way.This process was repeated for seven generations,at which point the average number of errors for 14 trials was 36.This experiment demonstrates that

A) learned behavior cannot be inherited.
B) natural selection has a role in the evolution of fixed action patterns but not in the evolution of behavior involving learning.
C) maze- learning ability has a genetic basis.
D) maze- learning ability depends mainly on early contact with adept parents.
