For someone planning to exercise in four hours, the appropriate carbohydrate intake is critical in optimizing performance and ensuring energy availability. Consuming about 4 grams of carbohydrates per kilogram of body weight is recommended in this timeframe to adequately load glycogen stores, enhance endurance, and sustain energy levels during the workout.

This higher intake is beneficial particularly when the exercise is expected to be prolonged or of high intensity, as it helps to maximize muscle and liver glycogen levels before engaging in physical activity. It is also essential to consider individual variability, including overall fitness level, duration, and intensity of the planned exercise.

The other options suggest lower carbohydrate amounts, which may not adequately prepare the body for a more intense or prolonged exercise session. Lower carbohydrate intake could lead to suboptimal performance, fatigue, or decreased endurance, illustrating why the 4 g/kg recommendation is the most suitable choice for pre-exercise nutrition in this scenario.
