The preservative of choice in this poisoning:: (A) Rectified spirit, (B) Saturated solution of sodium chloride, (C) Formalin, (D) Sodium flouride
Answer is B. The most commonly used preservative for viscera is saturated solution of common salt (NaCl) because It is easily available, cheap and effective preservative.
