Which type of exercise includes activities performed to enhance fitness?

The correct option highlights leisure-time physical activity as the type of exercise specifically aimed at enhancing fitness. This category encompasses activities that individuals voluntarily engage in during their free time with the intention of improving their physical health, strength, cardiovascular fitness, and overall well-being. Examples include jogging, swimming, cycling, or participating in group fitness classes.

In contrast, household chores are generally necessary tasks that may involve physical exertion but are not primarily focused on fitness enhancement. Similarly, passive recreational activities, such as watching TV or playing video games, do not contribute to physical fitness at all. Occupational tasks, while they can sometimes involve physical activity, are typically performed as part of job responsibilities and may not specifically target fitness. Thus, leisure-time physical activity is distinct in its primary goal of enhancing fitness levels.
