Default value in drop down list

Hello,

I am new to forms and I am playing around a bit now to get acquainted with the tool. 
What I have is a drop-down list, and depending on the chosen option I go to the next question or to the end of the form, so far so good. 

Now I want to make it more user friendly and set a default value in the dropdown list, this would save most users a click. 

So, the questions is, how do I set a default value in a drop down list in Microsoft Forms??
