70% to pass

Radiation spreads a fire by _______________.

A burning liquids flowing into another space
B heated gases flowing through ventilation systems
C transferring heat across an unobstructed space
D transmitting the heat of a fire through the ship's metal
AI Explanation

The correct answer is C) transferring heat across an unobstructed space. Radiation is the transfer of heat through electromagnetic waves, which can spread a fire by transferring heat across an unobstructed space. This allows the fire to spread without direct contact or flow of heated gases. The other options are incorrect because they describe other mechanisms of fire spread, such as burning liquids, heated gases through ventilation, or heat transfer through the ship's metal structure.
