Answer:
The correct answer is option B-thalamus.
Explanation:
Thalamus is a small olive shaped structure located in the brain beneath the cerebrum.
Thalamus serves as a relay station of the brain which has an important role in directing the sensory input signals to the appropriate location in the cerebral cortex of the impulses travelling from the body, ears, eyes and other senses (except for smell).
This happens as the thalamus is subdivided into a number of nuclei which deals with analyzing particular information and then sending the information from that nucleus to cerebral cortex.
Thus, option B-thalamus is the correct answer.
