The purpose of a propeller guard is to protect people in the water against propeller strikes. A propeller can cause serious injuries if it comes into contact with a person who has fallen overboard or is swimming near a boat. By enclosing the propeller area or placing a barrier around it, the propeller guard minimizes the risk of accidental injury to individuals in the water, making boating safer for everyone.

While enhancing vessel speed, improving fuel efficiency, and maximizing turning capabilities are important considerations in boat design and operation, they do not pertain to the specific safety function that a propeller guard serves. The primary focus of a propeller guard is safety, particularly in preventing injuries in situations where people are in close proximity to the propeller, thereby making option B the most relevant and correct answer.
