The porous membrane used in reverse osmosis plant is made up of :
Show Hint
In exam questions, if you see a slight typo like "Cellulose Acetone" instead of "Cellulose Acetate", choose it if it's clearly the intended answer among unrelated distractors.

- Cellulose acetone
- Potassium nitrate
- Mercuric iodide
- Starch

The Correct Option is A
Solution and Explanation
Reverse osmosis requires a semi-permeable membrane that allows solvent to pass but blocks solute.
The most common material used for this membrane is Cellulose Acetate.
Option (A) says "Cellulose acetone", which appears to be a typo for Cellulose Acetate found in the original exam paper (confirmed by Hindi version "Cellulose Acetate").
Options B, C, and D are chemical salts or carbohydrates not typically used as membrane films for RO.
Therefore, (A) is the intended correct answer.
