In Hibernate, making a property read-only from the application side (while still loading it from the database) is achieved by setting insert="false" and update="false" in the mapping XML or annotations. This tells Hibernate to retrieve the property value when loading objects but never include it in INSERT or UPDATE statements. Option A correctly states this. Options B and C use incorrect attribute names (should be 'insert' and 'update', not 'isinsert' and 'isupdate'), making them invalid.
