The option is designed to give the opportunity to stretch out the field if needed

That is the defense's objective - stretch the play out until you run into the sideline.

The QB's objective is to, if possible, get the ball as quickly as possible to the trail back without allowing the defender who is closest to the QB to be involved in the tackle. The RB then is supposed to square his shoulders to the line and find a hole.
