Studies suggest that there is a positive correlation between intelligence and the
a) brain's rate of glucose consumptionb) brain's production of endorphinsc) neural processing speed in the braind) the brain's ability to process language in the right rather than the left hemispheree) size of the brain's synaptic gaps

C. Neural processing speed in the brain

Explanation:

Neural processing speed determine the time that a person need in order to do a certain level of mental tasks. When solving a complicated problems, sometimes we need to pass through several different mental process before eventually come up with the solution. People with higher neural processing speed will finished the mental processes a lot faster and can come up with multiple solutions with the same time frame as people with slow neural processing speed.
