Final answer:
Speed is not one of the health-related components of fitness; it is a skill-related component. Hence, option (a) is correct.
Step-by-step explanation:
The health-related components of fitness include cardiovascular endurance, flexibility, and body composition. These components are related to how well the systems of the body operate to keep someone healthy.
Speed is a skill-related component of fitness rather than a health-related component. Health-related components of fitness focus on aspects that contribute to overall well-being and reduced risk of chronic diseases. These components typically include cardiovascular endurance, flexibility, muscular strength, muscular endurance, and body composition.
In contrast, speed is considered a skill-related component, emphasizing the ability to perform movements quickly and efficiently. While speed can be valuable in various activities and sports, it is not directly related to overall health and fitness in the same way as the components mentioned above. Therefore, speed is not one of the health-related components of fitness.
