[2025-10-02T07:22:39.757516] [PI reasoning] **Finalizing the answer on TTN**

I'm having trouble retrieving generic textbooks, but I found a 1981 article discussing radiological signs of TTN, specifically mentioning the "marked small interlobar fissure sign." I think Option C is correct here. I need to include in-text citations, possibly using [Ponhold, 1981]. My reasoning is that TTN presents prominent interlobar fissures and features related to RDS. I’ll create a concise answer with 1-3 sentences and include those citations.
