For this question, start with the A-Level concept in Surface area to volume ratio, then connect it to the scenario using exchange and a clear cause-and-effect chain. This variation checks whether the learner can turn the approved objective into a coherent exam response with clear biological reasoning. Distractors usually fail because they reverse the mechanism, use the wrong scale of organisation, or describe a related topic without answering the exact objective. This also helps avoid confusing similar A-Level terms that share vocabulary but test different biological reasoning.
