Answer: (C)
Rats can learn to run complex mazes even without food rewards present.
Step-by-step explanation:
Biological predisposition to learning is brought about by an internal inherited quality that increases the likelihood of having a condition or exhibiting a certain pattern of behavior.
It occurs in humans and animals and has to do with genes passed down from parents to children.
In this case, the genetical makeup of the rats can cause them to learn to behave in a certain way over time.
