Which listed substance is a lead salt used as a precursor to dangerous drugs?

• A. Pseudoephedrine
• B. Lead Acetate
• C. Lithium + Anhydrous Ammonia
• D. Iodine + ephedrine or pseudoephedrine or red phosphorus

Answer: (B)

The main idea is recognizing which substance is a lead salt and that such salts can be listed as precursors to illicit drugs. Lead acetate is a compound that contains lead as a cation with acetate; it is the one among the options that fits the description of a lead salt. In the regulatory context, even less common reagents like lead salts can be controlled precursors because of their potential role in illicit synthesis and their toxicity. The other choices are not lead salts, and they describe other well-known drug‑manufacturing methods or non-lead reagents, so they don’t fit the criterion of “a lead salt used as a precursor.”
