A Correct answer
Explanation
A. Cerebrospinal fluid is a clear liquid produced within spaces in the brain called ventricles. Like saliva, it is filtrate of blood. It is also found inside the subarachnoid space of the meninges which surrounds both the brain and spinal cord.
B. Pleural fluid is a thin translucent fluid that fills the cavity between the parietal(outer) and visceral(inner) pleural layers surrounding the lungs.
C. Synovial fluid also called synovia is a vicious, non- Newtonian fluid found in the cavities of synovial joints.
D. Aqueous is a thin, watery fluid located in the anterior and posterior chambers of the eye.
So, the correct answer is "Cerebrospinal fluid".
