Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
The acid base reaction is generally neutralisation reaction.

Lewis acid is one which accepts the lone pair and Lewis base is one which donates electron pair.

But according to the Lewis acid base theory formation of coordinate covalent bond in neutralization.

$N H_{3}$ is Lewis base while $B F_{3}$ is Lewis acid.

Option A is correct,
