A
Left Hemisphere
B
Right Hemisphere
C
Brain Stem
D
Thalamus
Explanation: 

Detailed explanation-1: -The brain is divided into symmetrical left and right hemispheres. Each hemisphere is in charge of the opposite side of the body, so your right brain controls your left hand. The right hemisphere also takes in sensory input from your left side and vice versa.

Detailed explanation-2: -Since language itself is uniquely human, this reinforced the idea that brain asymmetry more generally is a distinctive mark of being human [3]. Because the left hemisphere also controls the dominant right hand, it came to be widely regarded as the dominant or major hemisphere, and the right as nondominant or minor.

Detailed explanation-3: -Additionally, people are said to prefer one type of thinking over the other. For example, a person who is “left-brained” is often said to be more logical, analytical, and objective. A person who is “right-brained” is said to be more intuitive, thoughtful, and subjective.

Detailed explanation-4: -The incidence of right-hemisphere language dominance was found to increase linearly with the degree of left-handedness, from 4% in strong right-handers (handedness = 100) to 15% in ambidextrous individuals and 27% in strong left-handers (handedness =-100).
