D) Zantac

Xanax is a benzodiazepine that is known to cause intense withdrawal symptoms when stopped suddenly, including anxiety, tremors, seizures, and in severe cases, delirium and death. Librium and Valium are also benzodiazepines but are less potent than Xanax and therefore have less severe withdrawal symptoms. Zantac is not a benzodiazepine, it is a medication used to treat gastrointestinal issues.
