[2025-09-30T10:32:00.891199] [PI reasoning] **Analyzing radiographic density factors**

I’m considering factors that influence radiographic density. First off, tube current (mA) definitely affects exposure and density, as does kilovoltage (kVp). Cone angulation seems related to beam direction but might not directly impact density, though it can affect geometry. Object thickness does have a clear effect on density since thicker objects absorb more radiation. Ultimately, cone angulation likely doesn't affect density; the key contributors are mA, kVp, and object thickness, so I think the answer is C.
