Answer

Answer:

B. a substance that donates electrons to form a covalent bond

Brief Explanation:

A Lewis base is defined as an electron - pair donor. It donates electrons to form a covalent bond with a Lewis acid (an electron - pair acceptor). A substance that donates a proton is a Brønsted - Lowry acid. A substance that accepts electrons to form a covalent bond is a Lewis acid. A substance that when dissolved in water increases hydrogen ion concentration is an Arrhenius acid.
