Lewis base is a substance that dissolved in water increases hydrogen ion concentration.
This is a chemical substance which is slippery to touch and reacts with acids to form salt.
A lewis base is capable of donating its lone pair of electrons thereby resulting in its ability to increases hydrogen ion concentration when in water.

A Lewis base is a substance that donates electrons to form a covalent bond. Therefore, option B is correct.
A Lewis base is a type of molecule or ion that has a pair of electrons. It can donate electrons to another atom or molecule to form a chemical bond. The concept of Lewis bases was introduced by the American chemist Gilbert N. Lewis in 1923, as part of his theory of chemical bonding.
In a Lewis acid-base reaction, the Lewis base (electron-pair donor) reacts with a Lewis acid (electron-pair acceptor) to form a new compound. Lewis bases are important in many chemical reactions, including acid-base reactions, coordination complexes, and redox reactions. Examples of Lewis bases include ammonia (NH3), water (H2O), and chloride ions (Cl-). Therefore, option B is correct.
