Whoa, this exam is really putting my SQL skills to the test! I'm going to go with the answer that sounds the most complicated - B, three rows and four columns. Gotta keep 'em on their toes, am I right?

Wait, are we supposed to count the tables or the columns? I'm so confused, I'm just going to guess and pick A. Maybe I'll get lucky!

Hold up, is this a trick question or what? I'm gonna go with the classic C, four rows and two columns. Might as well play it safe, right?

I agree with Stephen, because a FULL JOIN combines all rows from both tables.

Hmm, looks like we need to understand the concept of a FULL JOIN to answer this one. I'm going to go with D, four rows and four columns - that seems to make the most sense based on the table structures.
