Based on the feature description and task, the possible values for the feature "loan" are "no" and "yes". 
For the target class "no", the feature "loan" can take the values "no" and "yes". This means that clients without a personal loan can also subscribe to a term deposit.
For the target class "yes", the feature "loan" can also take the values "no" and "yes". This suggests that having a personal loan does not necessarily prevent clients from subscribing to a term deposit.
