The correct answer is d. Uniqueness.

In the context of a DBMS (Database Management System), a transaction must have the following properties, often referred to as ACID properties:

a. Atomicity: This means that a transaction must be treated as a single, indivisible unit of work. In other words, either all of its data modifications are performed, or none of them are.

b. Consistency: This ensures that a transaction brings the database from one valid state to another. The database should satisfy a specific set of constraints before and after the transaction.

c. Isolation: This property ensures that the concurrent execution of transactions results in a system state that would be obtained if transactions were executed serially, i.e., one after the other.

However,

d. Uniqueness: This is not a property of a transaction in a DBMS. Uniqueness is a property that can be set on a database column to ensure that no two rows in the table can have the same value in that column. But it's not a property of the transaction itself.
