AVertical.
BCombination.
CHorizontal.
DParallel.
AI Explanation

The correct answer is B) Combination. The air flow depicted in figure 1 of the illustration SF-0013 represents a combination ventilation system, which uses both vertical and horizontal air flow patterns. Combination ventilation systems are commonly used in marine vessels to provide effective air circulation and prevent the buildup of stagnant air pockets. The other answer choices are incorrect because vertical ventilation only uses a vertical air flow (option A), horizontal ventilation only uses a horizontal air flow (option C), and parallel ventilation uses air flows that move in parallel directions (option D), which is not what is shown in the illustration.
