The "immediate" effect of a reaction?

[lightng]

This question has me completely stumped. Apparently the production of a ketone body can lead to an increase in the pH? Can anyone further explain this to me? The Altius explanation doesn't make much sense

This is an instance where you should rely on the passage information. They give you the reaction, try not to rely on outside knowledge. Yes, the production of ketone bodies does not lead to an increase in pH, it leads to a decrease in pH. They're not asking about that in this question though.

Both Acetoacetate and BHB are ketone bodies. They're specifically asking about the conversion from Acetoacetate to BHB which consumes to H+ ions according to the figure given. Consuming H+ takes it out of solution and increases the pH (lower concentration of H+).
