The Idea That Some People Are Right-Brained and Some People

The idea that some people are right-brained and some people are left-brained

A) is correct; some people use the left hemisphere for all tasks and some use the right.
B) is wrong because most people only use 10% of their brains and that 10% is almost always in the left hemisphere.
C) is correct and based on the fact that small neurons are constantly maturing so that only 10% of the neurons in only one hemisphere are mature at any given time.
D) is wrong because all tasks involve both hemispheres to some extent.
