I didn't knew the answer for this question. But based on the elimination I eliminated A and B. Because option A is table created successfully and Option C is again table created successfully but some condition. It gives way eliminate both A and B. I feel writer should have given option d may be closer to B made this question more interesting.

I answered a QotD correctly and I didn't guess! I am pretty new to SQL development (~6months) but I could see straight away there was an issue with the two IDENTITY.

These questions are really helping me improve, keep up the good work.

Good question. You almost got me because of the lack of caffeine in my system, but at the last moment I noticed the other identity field.

Everything is awesome!

Good clear question.

It's surprising that almost a quarter of people got it wrong. Maybe a lot of people don't use identity columns, so don't know the rules about them?

Again, I got the right answer for the wrong reason. The fact that the topic was IDENTITY should have been a tip-off. But I'd never encountered the References keyword before, and when I looked that up, I saw it was used to create a foreign key, meaning to another table. How could this work when it was referencing a table which at that point didn't even exist? But it does, as I found out after removing the second Identity field.

I would have expected higher than 75% correct on this question. But then again, I use identity columns all the time. Good back to basics question. Thanks!
