[2025-10-02T06:16:59.844128] [PI reasoning] **Choosing the best option for CLED media**

I need to determine the best option for why CLED media is better than MacConkey media. CLED, which stands for Cysteine Lactose Electrolyte Deficient agar, is used for urinary bacteriology and effectively inhibits swarming of Proteus species. This is its key advantage over MacConkey media, which does not inhibit swarming. So, option B is the right choice because CLED prevents this swarming. I'll need to reference literature to support this reasoning.
