Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: When poisoning is suspected, the viscera must be preserved in a medium that does not chemically alter the poison and does not interfere with later analysis.
Step 2: The standard preservative for toxicological viscera is a saturated solution of common salt (sodium chloride), so option (d) is correct.
Step 3: Rectified spirit (alcohol) is avoided because it can itself be a poison and confounds analysis. It is used only when alcohol is not the suspected agent and no other preservative is available.
Step 4: Formalin denatures proteins and chemical toxins and would mask or destroy the poison, so it is never used for toxicology. Glycerine is also not used. Hence the answer is saturated salt solution.
