Coagulation necrosis is primarily characterized by cellular death due to a loss of blood flow, leading to an inadequate supply of oxygen and nutrients to the affected tissues. This type of necrosis is often associated with ischemia or infarction, where the blood supply to a particular area is drastically reduced or completely interrupted.

In coagulation necrosis, the cellular architecture remains relatively intact for a period of time, which is why it is often observed in solid organs such as the heart, kidneys, and spleen after an injury. The necrotic tissue appears firm and takes on a pale appearance due to the lack of blood flow, contrasting with other types of necrosis, where there may be more extensive tissue breakdown or liquefaction.

The other options point to processes that are not the primary characteristic of coagulation necrosis. While the presence of infection and inflammation might occur in other forms of necrosis, it is not a defining feature of coagulation necrosis itself. Similarly, the formation of fluid-filled pus typically relates to liquefactive necrosis resulting from bacterial infection, and rapid cell death may be more closely associated with other processes rather than the gradual onset characteristic of coagulation necrosis.
