The term that best describes the stage when a fire is fully under control is "Under Control." This terminology indicates that the fire has been managed to a point where its spread has been halted and it is no longer an immediate threat to the structure or environment. Firefighters often use this designation to communicate that they have successfully subdued the flames and can now focus on extinguishing any remaining hot spots, conducting search and rescue operations, or performing damage assessments.

In contrast, "Extinguished" would suggest that the fire has been completely put out and is no longer burning at all, which is a step that usually follows the fire being placed "Under Control." "Combusted" refers to the chemical process of burning and is not typically used to describe the status of fire control. The term "Secured" can imply that an area is safe from further fire spread, but it does not specifically indicate that the fire itself is under control; it may also relate to securing the scene for investigation or ensuring that no additional risks are present. Therefore, "Under Control" most accurately represents the condition when the fire has been managed effectively but not necessarily extinguished.
