**Scenario Analysis:**
A DBMS enforces an UPDATE SET-TO-NULL option on referential integrity between the SELLER and REALTOR tables. A change is attempted in the REALTOR table, updating the RealtorID in the third record from R3 to R5. Consider the impact of this update:
**Options:**
1. Value R5 appears once in the column RealtorID in REALTOR, and value R5 appears once in column RealtorID in table SELLER.
2. Value R5 appears once in column RealtorID in REALTOR, and value R5 does not appear in the column RealtorID in table SELLER.
3. Value R5 does not appear in column RealtorID in REALTOR, and value R5 appears once in column RealtorID in table SELLER.
4. Value R5 does not appear in column RealtorID in REALTOR, and value R5 does not appear in column RealtorID in table SELLER. Also, value R5 appears once in column RealtorID in REALTOR, and value R5 appears twice in column RealtorID in SELLER.
This setup encourages critical thinking about referential integrity constraints and the effects of updates within relational databases.
