Final answer:
A building that stores combustive materials in the furnace room would be considered a C) high-risk property for property insurance.
Step-by-step explanation:
From an underwriting standpoint, a building that stores combustive materials in the furnace room would likely be considered a high-risk property for property insurance. Combustive materials pose a significant fire hazard, which increases the likelihood of a loss for the insurer. In such cases, insurance companies may charge higher premiums or impose stricter conditions to mitigate the risk.
