Which item is described as 'Iodine + ephedrine or pseudoephedrine or red phosphorus'?

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

Answer: (D)

This phrase points to a methamphetamine manufacturing method. Ephedrine or pseudoephedrine are common starting materials, and iodine with red phosphorus is a classic combination used to reduce and convert those starting materials into methamphetamine. In other words, this is describing the illicit synthesis recipe or set of precursors used in meth production, not a single chemical. The other items listed are individual chemicals with unrelated uses, so they don’t fit this specific synthesis context.
