- Arsenic
- Mercury
- Lead
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding heavy metal toxicity.
Heavy metals can accumulate in the human body and disrupt physiological functions, especially the nervous and digestive systems.
Step 2: Effects of mercury.
Mercury causes haemolysis, gastrointestinal distress, abdominal pain, chest pain, and neurological disorders.
Step 3: Comparing options.
(A) Selenium toxicity causes hair and nail loss.
(B) Arsenic causes skin lesions and cancer.
(C) Mercury causes haemolysis and severe digestive symptoms.
(D) Lead affects the nervous system and causes anemia.
Step 4: Conclusion.
The correct answer is (C) Mercury.
