323367 Read the Statement - A and Statement - B carefully to mark the correct options given below:
Statement A :
A methanol-poisoned patient is treated by giving an intravenous infusion of diluted ethanol.
Statement B :
Ethanol reduces the action of enzymes which converts the methanol into toxic products, by competitive inhibition, thus allowing time for the kidneys to excrete methanol.

1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
