Option 3 states that "Animal insulin exhibits similarities to human insulin." However, this statement is not true. Animal insulin and human insulin have slight structural differences, although they share functional similarities. Animal insulin can be used to treat diabetes in humans, but it is not identical to human insulin.

Hence, the correct answer is option 3.
