**Core Concept**
Apoptosis is a regulated process of programmed cell death, essential for maintaining tissue homeostasis and eliminating damaged or unwanted cells. This process involves a series of molecular and cellular events, including DNA fragmentation, chromatin condensation, and membrane blebbing.

**Why the Correct Answer is Right**
Apoptosis is characterized by the activation of caspases, a family of cysteine proteases that play a central role in executing the cell death program. The mitochondrial pathway of apoptosis involves the release of cytochrome c from mitochondria, which then binds to Apaf-1 and triggers the formation of the apoptosome, a multiprotein complex that activates caspase-9. The caspase cascade ultimately leads to the cleavage of cellular substrates, including DNA repair enzymes and structural proteins, resulting in cell death.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because apoptosis is indeed characterized by DNA fragmentation, which occurs as a result of the activation of caspases and the cleavage of DNA repair enzymes.
* **Option B:** This option is incorrect because chromatin condensation is a hallmark of apoptosis, occurring as a result of the activation of caspases and the cleavage of structural proteins.
* **Option C:** This option is incorrect because membrane blebbing is a characteristic feature of apoptosis, resulting from the activation of caspases and the cleavage of membrane-associated proteins.

**Clinical Pearl / High-Yield Fact**
A key feature of apoptosis is that it occurs in a controlled and non-inflammatory manner, allowing for the efficient removal of damaged or unwanted cells without inducing an immune response. This is in contrast to necrosis, which is a form of cell death that occurs due to acute cellular injury and is often accompanied by inflammation.
