[2025-10-02T06:13:08.367574] [PI reasoning] **Clarifying TOF Characteristics**

I didn't quickly find a crisp statement, but it looks like tetralogy of Fallot (TOF) is still relevant. A previous result mentions that only certain heart conditions are associated with a normal or slightly enlarged heart size. TOF is also linked to decreased pulmonary perfusion. So, the answer is likely D. Now, I’ll gather evidence showing TOF with oligemic lungs and a normal heart to support this reasoning.
