Final answer:
Character large objects (CLOBs) in databases can have a maximum size that varies depending on the database and the amount of disk space allocated for it. Different databases may have different maximum sizes for CLOBs. In regards to character large objects (CLOBs) in databases, the correct answer is option c.)
Step-by-step explanation:
Unlike standard character columns, CLOBs are designed to store large amounts of text data, such as documents or entire books. The maximum size of CLOBs can vary depending on the database and the amount of disk space allocated for it. Therefore, the max size in many cases can be unlimited.
It is important to note that different databases may have different maximum sizes for CLOBs, so option d.) is also true. However, option a.) is not true because there is no constant set max size for CLOBs due to compliance with ANSI SQL, and option b.) is not true because there is a maximum size for CLOBs.
