Final K-1 due to merger. How to indicate disposition?

I was a passive owner in a business (Business 1). That business was merged with another business (Business 2) as of 12/31/17. I have received my final K-1 from Business 1. In 2018, I will have ownership in Business 2 as a result of the merger. I know to select "This partnership ended in 2017" but am stuck when it comes to selecting disposition. Which method should I choose? 

No Entry

Complete Disposition

Disposition was not via sale

Sold and am receiving payments
