Solution

The correct options are
A accepts a lone pair of electron (Lewis concept)
B donates a proton (Lowry and Bronsted concept)
A Lewis acid is any substance that can accept a pair of nonbonding electrons. In other words, a Lewis acid is an electron-pair acceptor.
A Lewis base is any substance, such as the OH- ion, that can donate a pair of nonbonding electrons. A Lewis base is therefore an electron-pair donor.

A Bronsted-Lowry acid is defined as anything that releases H+ ions. A Bronsted-Lowry base is defined as anything that accepts H+ ions.
