AThe number of zones reporting gives an indication of the size of the fire or the extent to which it has spread.
BThe number of zones reporting gives an indication of the rate of development of the fire.
CThe number of zones reporting gives an indication of the intensity of the fire.
DThe number of zones reporting gives an indication of the stage of development of the fire.
AI Explanation
The correct answer is A) The number of zones reporting gives an indication of the size of the fire or the extent to which it has spread. This is correct because the number of zones reporting active fire, smoke, or heat detection indicates the physical area affected by the fire. More zones reporting indicates the fire has grown and spread to a larger portion of the protected space, while fewer zones indicates a smaller, more localized fire. The number of zones does not directly reflect the rate of fire growth, intensity, or stage of development, which is why options B, C, and D are incorrect.
