Answer:
B). Jenny's amygdala has matured before her frontal lobes.
Explanation:
As per the question, Jenny's error would be elaborated by the description that her amygdala(part of brain responsible for emotions, memory, and instincts in humans) has reached maturity before her 'frontal lobes'(part of brain responsible for intellectual activities like thought, reasoning, attention, consciousness, etc.). Jenny is mistaken because her emotional aspect has developed or become active before gaining the ability to consciously think, judge or execute a behavior. Therefore, <u>option B</u> is the correct answer.
