b

Explanation:

Answer 2

OrderID + ProductID is an example of a composite key in a database table. The correct option is 4.

What is composite key?

A composite key is a key in a database table that consists of two or more columns that uniquely identify each row.

In a database table, a composite key is the combination of OrderID and ProductID in a table that tracks sales transactions.

Because a single order can contain multiple products and multiple orders can contain the same product, neither column can uniquely identify a row by itself.

However, by combining the two columns, each row can be uniquely identified, ensuring that the data is accurate and complete.

Similarly, a combination of CustomerID and ProductID might be used in a sales system to track the products purchased by each customer.

Thus, the correct option is 4.
