Aprimary key is a column that holds a unique value for each row, and can be used to identify specific rows? (true/false)

The statement is: True.

Explanation:

A primary key is useful to identify each row within a table. The primary key constraint makes sure rows are unique since they can be used once per table and it cannot be blank, a "null" value or duplicated. The content of the table typically represents information that should not be repeated such as individuals' full name, phone number or Social Security Number (SSN).
