Verified step by step guidance

Understand the role of cerebrospinal fluid (CSF): CSF is a clear fluid that surrounds the brain and spinal cord, providing cushioning, nutrient delivery, and waste removal.

Identify the structure responsible for CSF production: The choroid plexus is a specialized structure located within the ventricles of the brain that produces CSF. It consists of ependymal cells and capillaries.

Eliminate incorrect options: The dura mater is a tough outer membrane that protects the brain and spinal cord but does not produce CSF. The corpus callosum is a bundle of nerve fibers connecting the two hemispheres of the brain, and the cerebral aqueduct is a narrow channel that allows CSF to flow between ventricles, but neither produces CSF.

Focus on the correct structure: The choroid plexus actively secretes CSF into the ventricles, where it circulates through the central nervous system.

Conclude the reasoning: Based on the function and location of the choroid plexus, it is the correct answer for the structure primarily responsible for CSF production.
