Solution

The correct option is E accept a proton
A Bronsted-Lowry acid is a "proton donor" and a base is a "proton acceptor."
$H A + H_{2} O \to H_{3} O^{+} + A^{-}$
The $H A$ is an acid because it is donating a proton (hydrogen ion) to the water. The water is a base because it is accepting a proton from the $H A$ .
A Lewis acid is an electron pair acceptor and A lewis base is an electron pair donor.
