The correct answer is A) reduce the possibility of carryover. Steam baffles are used in the steam drum of a water-tube boiler to reduce the possibility of carryover, which is the undesirable entrainment of water droplets in the steam leaving the drum. Carryover can lead to moisture in the steam lines and potential damage to downstream equipment. The steam baffles create a more quiescent flow pattern in the steam drum, allowing the water droplets to separate from the steam before it exits the drum. The other answer choices are incorrect because they do not accurately describe the primary function of steam baffles in a water-tube boiler. Options B, C, and D describe other components or purposes not directly related to the role of steam baffles in reducing carryover.
