Answer:
C : CH₃OH
Step-by-step explanation:
According to the concept of Bronsted - Lowry -
An acid is a substance , that can give a proton .
A base is a substance , that can take a proton .
According to the reaction given in the question ,
CH₃OH + HI --> CH₃OH₂⁺ + I⁻
From , the above reaction ,
It is visible that , the reactant CH₃OH accepts a proton and forms CH₃OH₂⁺ , thereby acting as a base ,
And , HI act as an acid , as is losses a proton and becomes I⁻ .
Hence ,
In the above reaction , CH₃OH act as a base .
