I believe option B is also important for testing the SQL queries with sample data.

I think having only 2 columns in the DEPARTMENTS table might be enough for a basic setup.

I'm not sure about option A, do we really need only 2 columns in the DEPARTMENTS table?

I agree with having primary and foreign keys is important for data integrity.

I think option D is true because it mentions creating primary and foreign keys.

Good point, Elke. Option B does seem a bit out of place compared to the other options. Maybe it's a trap answer.

Hmm, I'm not too sure about option B though. Inserting 10 rows of random sample data? That seems a bit specific for a question like this.

You're right, Helga. Option D mentions that there will be a foreign key linking the EMPLOYEES table to the DEPARTMENTS table. That's a key piece of the puzzle.

Yeah, those options make sense to me too. But what about the foreign key relationship between the tables? That's an important detail to consider.

I agree, it does seem pretty straightforward. I'm leaning towards options A and C being true, since those describe the table structure.
