Correct answer: B — Dissolve both sachets in a total of 250 mL water; this does not replace usual fluid intake

Each sachet is dissolved in 125 mL water, so two sachets require 250 mL when prepared together. The reconstituted solution does not replace normal fluid intake; an individual fluid restriction would need separate clinical advice. Concentrating two sachets into the water volume for one, changing the labelled ratio or swallowing powder dry does not follow the product directions.
