A database table contains group I'd and group name fields. Which field can be the primary key of the table

The field that has the same name as another field on another group

The Group_ID field can be the primary key of the table.

Explanation:

When dealing with databases we need to choose primary key for every table. Primary key is something that uniquely identifies data in that table. It means that primary key can appear only once in that table and for each data it is different.

In our case it is Group_ID. This is field that can easily be made different each time. It is possible that Group_name contains more groups with same name.
