**Core Concept**
Coagulative necrosis is a type of accidental cell death that occurs due to prolonged ischemia, leading to the preservation of cell outlines and a relatively intact cellular architecture. This process is commonly seen in solid organs such as the heart, liver, and kidneys, where the tissue architecture is maintained for a period after cell death.

**Why the Correct Answer is Right**
Coagulative necrosis is characterized by the denaturation of proteins and the coagulation of cytoplasmic proteins, resulting in a firm, gelatinous appearance of the affected tissue. This process is mediated by the activation of lysosomal enzymes and the breakdown of cellular membranes. The preservation of cell outlines is due to the resistance of the basement membrane and the extracellular matrix to enzymatic degradation. In contrast to liquefactive necrosis, coagulative necrosis does not involve the extensive breakdown of tissue architecture, allowing for the maintenance of cellular morphology for a longer period.

**Why Each Wrong Option is Incorrect**
**Option A:** Liquefactive necrosis is a type of necrosis that involves the breakdown of tissue architecture and the conversion of tissue into a liquid or gelatinous state, typically seen in brain tissue and other organs with a high lipid content. This type of necrosis is not the dominant feature of infarction in solid organs such as the heart and liver.
**Option C:** Chronic inflammation is a response to tissue damage or infection, characterized by the infiltration of immune cells and the production of pro-inflammatory cytokines. While inflammation may occur in response to infarction, it is not a histologic feature of the infarcted tissue itself.
**Option D:** Scar tissue is a result of the healing process after tissue damage or infarction, characterized by the deposition of collagen and other extracellular matrix components. While scar tissue may eventually form in the area of infarction, it is not a dominant feature of the infarcted tissue itself.

**Clinical Pearl / High-Yield Fact**
It is essential to distinguish between coagulative and liquefactive necrosis, as the former is often seen in solid organs such as the heart, liver, and kidneys, while the latter is typically seen in brain tissue and other organs with a high lipid content.

**✓ Correct Answer: B. Coagulative necrosis**
