The reaction of a lewis acid with a lewis base would most likely be accompanied by an increase in which item?
covalent bonds
hydronium ions
electron pairs
hydroxide ions

The correct option is COVALENT BONDS.

A Lewis acid is defined as a substance which accept a pair of electron while a Lewis base refers to a substance that donate an unshared pair of electrons to another chemical specie with which it shared the donated pair of electrons.

Lewis acid and Lewis base react together to form salt and water. This type of reaction is called neutralization reaction. The neutralization reaction of Lewis acid and Lewis base involves electron pairs transfer, thus, there is an increase in the number of covalent bonds during this reaction.

the correct answer is:

a. formation of precipitation
