Recall the definition of a Lewis base: a Lewis base is a species that donates an electron pair to form a bond.
Understand that a Lewis acid is the species that accepts an electron pair, while a Lewis base donates it.
Recognize that donating a proton (H\(\textsuperscript{+}\)) or increasing H\(\textsuperscript{+}\) concentration relates to Brønsted-Lowry acids and bases, not Lewis acids and bases.
Identify that the correct characteristic of a Lewis base is donating an electron pair to form a coordinate covalent bond.
Therefore, the statement 'It donates an electron pair to form a coordinate covalent bond' best describes a Lewis base.
