To enforce referential integrity, the database can return an error instead of doing the requested action or do the requested action and do the related changes to the related tables
Thus the answer is either a or b.
Explanation:
When the given data base in a table is valid and if it is consistent then it is called as referential integrity and it also refers to the consistency within the relationship. This type of database is much important because it will keep us introducing to the errors in the databases and it also checks if the reference from one table is equal to the other table.
The main function is to prevent the users from entering the wrong and inconsistent data. So in referential integrity the database will return the error instead of doing the required action or it can do the related changes to the related tables.

Superior memory.
Hyperthymesia, also known as extremely superior autobiographical memory (HSAM), is a disorder that causes people to be able to vividly recall an excessively high number of past events. Only 61 persons worldwide have been diagnosed with it as of 2021, making it incredibly rare. There is a difference between people with hyperthymesia and people who have other types of superior memory. People with superior memory typically employ mnemonic or similar rehearsing tactics to memorize long strings of information. People with hyperthymesia frequently recall intimate, autobiographical recollections of both important and unimportant events in their life. Although they can be able to recall the day of the week that a specific date fell on, hyperthymestics are not calendared calculators like some savants. Instead, hyperthymic recall is thought to be a subconscious process that is limited to a person's lifetime.
