I got this question in semester exam.

This question is from Mechanism of Action of Local Anesthetic in section Local & General Anesthetics, Opioid Analgesics, Drug Addiction and Drug Abuse of Drug Biotechnology

Answer 1

Right option is (d) Procaine

To explain: Procaine is used in dentistry when the patients have proven allergy to the amide group. Used intra-arterially, to treat the arteriospasm which might occur during intravenous sedation. It has excellent vasodilatory properties. The first and most potent local anesthetic agent is cocaine used topically.
