Cerebrospinal fluid (CSF) protects the brain, transports nutrients, and acts as a shock absorber but does not generate nerve impulses.

Cerebrospinal fluid (CSF) cushions the brain and spinal cord while also removing metabolic waste.

The choroid plexus, located in the ventricles of the brain, produces cerebrospinal fluid (CSF).

Cerebrospinal fluid (CSF) protects the brain and spinal cord from shocks and aids in nutrient transport but does not generate nerve impulses.

As explicitly described in Chapter 6 of the NCERT Class 10 textbook, the highly delicate organs of the central nervous system require incredibly robust protection to function without any physical disruption. The human brain, being a phenomenally complex organ responsible for a multitude of vital tasks, sits securely inside a hard, bony box generally called the cranium or skull. To provide further safeguarding, inside this bony structure, the brain is safely enclosed in a fluid-filled balloon. This fluid is known as the cerebrospinal fluid, which serves as a highly effective shock absorber against sudden jolts or physical trauma. Similarly, the spinal cord, which extends downwards from the brain and fundamentally handles reflex arcs as well as nerve impulse transmission, is structurally protected by the vertebral column, commonly referred to as the backbone, preventing any minor impacts from causing severe neurological damage. By acting as a liquid cushion, this cerebrospinal fluid perfectly functions as an incredibly reliable and essential shock absorber.

Go with C — Subarachnoid space. Within Structure and Function of Nervous System, that statement lines up with the standard definition and the usual exam wording you’ll see. In plain terms, Subarachnoid space is the option that correctly names the structure, process, or principle asked for in Structure and Function of Nervous System. Holding that picture in mind makes Subarachnoid space feel natural rather than something you only memorise. Link the term to a real body example (organ, tissue, or ion flow) so the idea stays concrete under exam pressure. A short mental diagram helps — start from stimulus or structure, follow the pathway, and stop at the functional result described by Subarachnoid space.
Ref: Animal physiology is Unit 7 of the CSIR NET Life Science Syllabus, covering core body systems. It accounts for roughly 10% of the total marks in Sections B and C.
