Final answer:
Atropine is not an antidote for benzodiazepine poisonings, potassium permanganate does not inactivate strychnine and cyanides, methanol is not an antidote for alcohol/ethanol poisonings, and paraffin oil does absorb/bind benzene, toluene, and phenols.
Step-by-step explanation:
a) Atropine is not a specific antidote used in case of benzodiazepines poisonings. It is actually used as an anticholinergic to manage the symptoms of nerve agent poisoning.
b) Potassium permanganate solution does not inactivate strychnine and cyanides. It is used extensively in water treatment.
c) Methanol is not a specific antidote used in case of alcohol/ethanol poisonings. It is highly poisonous and ethanol is given to methanol intoxicated patients as a competitive inhibitor of the enzyme alcohol dehydrogenase to prevent the formation of formaldehyde.
d) Paraffin oil does absorb/bind benzene, toluene, and phenols.
