Lyette has recently given birth to her first child. She decides

to start playing classical music near the baby's crib at night so that the child will develop greater intelligence. Which of the following may be an explanation for why such strategies appear to have some impact on the developing child?
A) These strategies are like "vegetables for the brain," and impact virtually every area of brain growth and development. This is why it is a good idea to play classical music for a child even before (s)he is born.
B) These strategies impact the use of echoic memory, which is distinctly tied to the ability to boost intellectual growth.
C) These strategies boost the activity of the temporal lobes, which are responsible for both hearing and intellectual development. Therefore, long-term intelligence improvement is likely to occur.
D) These strategies boost short-term arousal, which may help performance on mentally demanding tasks for a brief period of time; however, there is no evidence that they will impact long-term intelligence.
