The term "infarction" specifically refers to tissue death due to a lack of oxygen, which occurs when blood supply is restricted or blocked. This deficiency prevents adequate oxygen and nutrients from reaching the cells, leading to cell death and potential damage to the affected tissue.

Infarction is often associated with conditions such as myocardial infarction (heart attack) and cerebral infarction (stroke), where the interruption of blood flow is typically caused by a blockage in a blood vessel, often due to a blood clot.

The other options describe different processes or conditions that do not encompass the concept of infarction. For example, the temporary oxygen deficiency refers more to hypoxia, not irreversible tissue death. The process of blood clot formation pertains to thrombosis, which can lead to infarction but is not synonymous with it. An area undergoing inflammation involves the immune response to injury or infection, which may precede or accompany infarction but is distinctly different from the actual process of tissue death.
