If a DBMS enforces an UPDATE CASCADE option on the referential integrity constraint between CLIENT and AGENT in the HAPPY INSURANCE database, what will be the outcome after a user tries to change the AgentID value in the last record to A5?

a. Value A4 appears once in column AgentID in AGENT, and value A4 appears once in column ClientAgent in table CLIENT
b. Value A5 appears once in column AgentID in AGENT, and value A5 appears once in column ClientAgent in table CLIENT
c. Value A5 appears once in column AgentID in AGENT, and value A5 does not appear in column ClientAgent in table CLIENT
d. Value A5 does not appear in column AgentID in AGENT, and value A5 appears once in column ClientAgent in table CLIENT

Answer: this depends on the amount required to pay off the individual's card as well as how large the minimum payments are.if the amount is significantly large and the minimum payments are significantly small, then it will take a longer time to pay off the credit card.if the amount is significantly small and the minimum payments are significantly large, then it will take less time to pay off the credit card.hence, it would be difficult to answer true or false to this statment.however, for the purpose of this statement, it is most likely assumed that regardless of the amount to pay off the credit card the minimum payments would be quite large.therefore, the better option would be to pick 'true' as your answer.hope this ! : )have a lovely day! < 3
