In a Study by Fredman and Whitman (2008),mother-Raised and Human-Raised

In a study by Fredman and Whitman (2008) ,mother-raised and human-raised capuchin monkeys watched a human model use a screwdriver to remove a lid from a container and gain access to a food reward.In separate groups of both types of monkeys,the model removed the lid by either sticking the screwdriver in a hole located in the middle of the lid or by prying the lid off from the rim.The investigators found that:

A) only the human-raised monkeys learned by observation.
B) both groups learned by observation and both preferred sticking the screwdriver into the hole.
C) both groups learned by observation,but the human-raised monkeys were much more likely to pry the lid off from the rim.
D) both groups learned by observation,but the human-raised monkeys were considerably more likely to imitate the exact method the human model used.
