The correct answer is **C. Concentration**.
In an enclosed space, the concentration of coal dust can reach levels that are higher than in an open outdoor space. When the concentration of dust is sufficient, it can lead to a chain reaction and result in an explosion. In contrast, when coal dust is dispersed outdoors, it is diluted by the open air, reducing the potential for an explosive reaction.
