Ooh, this is a tricky one! I'm gonna have to go with my gut on this one and choose B) 11.2 (160). Sounds like a good middle-of-the-road option to me.

Alright, time to put on my thinking cap. I'm gonna go with C) 16.8 (240) - it just feels right, you know? Plus, it's a nice round number, which is always a good sign.

I'm not sure, I need to double check the calculations before making a decision.

I agree with Ariel, the flow rate and pressure values match up with option B.

Haha, this question is a real brain-teaser! I'm just gonna go with D) 25.2 (360) and hope for the best. Who needs to understand the actual formula, anyway?
