Step 1: The defining morphologic signature of apoptosis is the eosinophilic apoptotic body formed when a single cell shrinks and fragments after chromatin margination and surface blebbing.
Step 2: In the liver, such apoptotic hepatocytes are named Councilman bodies and are typically found in acute viral hepatitis, directly matching the concept of apoptosis.
Step 3: Gamna Gandy bodies are siderotic fibrocalcific nodules of an old splenic bleed and have nothing to do with single-cell programmed death.
Step 4: Russell bodies are intracytoplasmic immunoglobulin globules in plasma cells, again unrelated to apoptosis. Therefore Councilman bodies are the right answer.
