Acid is the one which is donate the proton in the reaction.
Conjugate acid-base pair differ by one proton. Conjugate base of an acid is the acid species remains after donates the proton.
In the given reaction, ethoxide is a base and toluene is an acid.
Ethanol is an acid and benzyl anion is a base.
The pKa value of toluen is 41 and the pKa value of ethanol 15.9.
The acid with larger pKa value is a weaker acid.
The equilibrium proceeds towards formation of weaker acid.
Therefore,
a) The weaker acid is toluene.
b) Its conjugate base is benzyl anion.
c) The species that predimate at equilibrium are A and B.
