Explanation

Roll-Up Summary fields can only exist in a Master-Detail relationship - they aggregate data from child records up to the master record. If Roll-Up Summary fields exist on the master object (in this case, the Project object), Salesforce will block the conversion from Master-Detail to Lookup because Lookup relationships do not support Roll-Up Summaries. The administrator must delete all Roll-Up Summary fields on the master object before the relationship type can be changed. A junction object (A) is used for many-to-many relationships, which is not relevant here. The lookup field having values (B) or being required (C) does not prevent the relationship type conversion.
