- Arsenic
Show Solution
The Correct Option is C
Solution and Explanation
Step 1: Forensic color associations of stomach contents help identify the poison: blue, green, yellow, black, white, and slate each map to specific agents.
Step 2: The blue shade corresponds to copper sulfate and to amytal (amobarbital) capsules, whose coloring tints the mucosa.
Step 3: From the listed choices, amytal sodium is the blue-producing poison, so it is the answer.
Step 4: Mercury would render a slate-grey appearance and arsenic shows white particles, neither of which is blue, ruling them out.
\[\boxed{\text{Amytal sodium}}\]
