Nah its B because they add lime to increase pH to assist coagulation/flocculation

That's not pH balancing though. pH balancing refers to adding acids and bases at the end to get your ideal pH.

Also, whilst we're on the topic, how the fck does everyone remember their answers so well?

We're allowed to take our question sheet from the exam, and I write my answers on the sheet first so I can double check later. I assume others do this.
