Which statement best describes necrosis?

Necrosis is accurately described as the death of tissue in a living organism, which is why this answer is the correct choice. Necrosis occurs due to various factors, such as lack of blood supply, infection, or injury, leading to cell death and subsequent tissue damage. This process is often characterized by inflammation and can have significant implications for the health of the organism, potentially leading to further complications if not addressed.

The other options do not accurately reflect the nature of necrosis. For instance, preservation methods aim to maintain the viability and integrity of tissues, contrary to what occurs during necrosis, where tissue becomes nonviable. Similarly, healthy tissue development refers to the process of growth and regeneration of tissues, which is in direct opposition to the concept of necrosis. Finally, while embalming involves preserving tissues after death, it does not relate to the live tissue that is undergoing necrosis, further differentiating it from the correct definition of necrosis.
