Option C is just a mess. Mixing the WHERE and HAVING clauses like that is a recipe for disaster.

I think option D is the correct one. It separates the WHERE and HAVING clauses properly.

Option C is definitely confusing. It's better to keep the WHERE and HAVING clauses separate.

Option D is the way to go! Putting the HAVING clause after the GROUP BY makes the most sense to me.

Option B looks like it might work, but the WHERE clause and HAVING clause are a bit confusing. I'll have to think about that one.

I believe option D will fail because the HAVING clause should come after the GROUP BY clause.

I agree with Magdalene. Option A seems incorrect due to the placement of the HAVING clause.

I think option A will fail because HAVING clause should be after GROUP BY.
