[2025-10-01T22:46:57.142225] [PI reasoning] **Explaining karyolysis**

I need to clarify some key terms related to pathology and histology. Karyolysis is the dissolution of nuclear chromatin, while pyknosis refers to nuclear shrinkage and increased basophilia. Karyorrhexis is the fragmentation of the nucleus. For our answer, I'll choose letter B because it aligns with these definitions. I might consider performing a quick search to find an article that supports this definition, but it might not be necessary.
