On a form wizard step what input type/s shall I use for when there are two options?

Ok so I have two options on a wizard step e.g. Option 1: Go to step A, Option 2: Go to step B.

What is the best input method to use in this situation?

The wizard generally has more complicated steps and utilises a next button. With this in mind, shall I maintain the use of the next button and offer two radio button options and a next button. This method retains the next button layout but mean the user has to select a radio button option and then click next (2 actions).

Or as it is a simple step shall I drop the next button and offer two buttons, each one going to their respective step. This version benefits from keeping the step down to one action.

See mockup below as to the two options I've mentioned (please ignore the styling):
