In table design view what are the first column of buttons used for A. Indicate Primary Key B. Indicate Current Row C. Both of above D. None of above

The correct answer is: A. Indicate Primary Key

The first column of buttons in table design view is used to indicate the primary key of the table. The primary key is a column or columns that uniquely identifies each row in the table.

The other options are incorrect because:

• Option B is incorrect because the first column of buttons does not indicate the current row. The current row is indicated by the dark gray background of the row.
• Option C is incorrect because the first column of buttons does not indicate both the primary key and the current row. It only indicates the primary key.
• Option D is incorrect because the first column of buttons is used to indicate the primary key.
