Your answer: —  ·  Correct: A
Explanation

The term “apoptosis” specifically refers to programmed cell death and encompasses the cellular and molecular mechanisms that control this process. Classical reviews and textbooks define apoptosis as a genetically regulated form of cell suicide that functions in development, tissue homeostasis, and removal of damaged cells [1]. Molecularly, apoptosis is mediated by defined signaling pathways—intrinsic (mitochondrial) and extrinsic (death-receptor)—and key effectors such as initiator and executioner caspases and regulatory Bcl-2 family proteins, which orchestrate orderly cellular dismantling without provoking inflammation. Thus, among the options given, apoptosis is the correct term for the cellular and molecular control of programmed cell death.
