Option Explicit makes sure that any Vairables you use are Pre-Defined, otherwise it'll give you an Error Message telling you it isn't.

It's useful for making sure you keep your Programs Tidy, it can also help if you make a Typo with a Vairable name.

If you don't use Option Explicit VB doesn't care if you create variables on the fly, i.e

A = 1

Instead of:

Dim A As Integer
A = 1
