Which of the following describes the appearance of normal CSF?

Explanation:
Normal CSF is clear and colorless because it contains very few cells and little protein. This transparent appearance indicates there’s no infection, inflammation, or blood breakdown products present. A cloudy appearance would mean more cells or protein, as seen with meningitis or inflammatory processes. Yellow CSF can result from xanthochromia due to bilirubin after a bleed or high protein, and greenish CSF can point to pus or certain infections. So the description of clear CSF best matches normal CSF.
