The appropriate isolation level for ensuring that an application can read the committed value of a row that is exclusively locked by another application is 'Cursor Stability with WAIT FOR OUTCOME clause.' Cursor Stability (CS) generally means that a row read by the application holds a lock on the current row, releasing the lock when the cursor moves to the next row. However, in cases where rows are locked due to an ongoing transaction, the WAIT FOR OUTCOME clause specifies to wait until the committing or rollback of those transactions to access the data, which ensures that only committed data is read.
