Option A looks like it might work, but it would also include customers with a satisfaction rate of 90 or above, which is not what we want.

Haha, option D looks like it's trying to use a date range for a numeric column. Nice try, but no cigar!

I'm not sure about option B, as it's trying to filter for a single value of 80 AND 90, which doesn't make sense.

User 4: I think option D is incorrect because the BETWEEN operator should have two separate values, not a range.

Option C seems to be the correct answer, as it selects the Customers2 relation by filtering the Satisfaction_Rate between 80 and 89 inclusive.
