In figure 1 of the illustration, fire would spread to compartment "B" by __________. SF-0013

Correct Answer: Option D — conduction

Conduction is the transfer of heat through solid materials. In shipboard fire scenarios, heat travels through bulkheads, decks, or structural steel from a fire in one compartment to an adjacent space. This mechanism can ignite combustible materials in the neighboring compartment even without direct flame contact or air movement.
