I'll go with C as well. Retrieving the minimum value seems like the most straightforward operation that wouldn't require too much compute power.

Ha! 'Assuming no queries have been executed previously?' What kind of trick question is this? I bet the answer is 'None of the above' since any SQL query is going to require compute power.

I'm not sure about this one. Aren't all of these operations going to require some level of computation? Even just fetching the data seems like it would involve compute resources.

But for MIN function, it doesn't require any computation, so it can be completed without queries.

But wouldn't calculating the minimum value also require computation?

I think the correct answer is C. Selecting the minimum order amount from the sales table doesn't require compute, as it's just retrieving the lowest value.
