**Core Concept**
Aseptic autolysis is a process where tissues undergo self-digestion due to the action of enzymes within the cells themselves, resulting in tissue breakdown without the presence of an external pathogen. This process is commonly observed in tissues that have undergone ischemia or infarction.

**Why the Correct Answer is Right**
Aseptic autolysis occurs due to the activation of lysosomal enzymes, such as cathepsins, which break down cellular components. In ischemic tissues, the lack of oxygen and nutrients leads to cellular injury, causing the release of these enzymes and subsequent tissue breakdown. The absence of an external pathogen is a key characteristic of aseptic autolysis.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not accurately describe aseptic autolysis. Aseptic autolysis is not primarily caused by external factors such as bacterial invasion.
**Option B:** This option is incorrect because it describes a different process, where external pathogens cause tissue breakdown.
**Option C:** This option is incorrect because it does not accurately describe the pathophysiology of aseptic autolysis.

**Clinical Pearl / High-Yield Fact**
Aseptic autolysis is a key feature of ischemic tissue injury, and understanding its pathophysiology is essential for diagnosing and managing conditions such as myocardial infarction and stroke.

**Correct Answer:** C.
