Answer:
Most likely busy adults who care about health and nutrition.
Explanation:
The reason why that it would target this is because it explains the heath benefits of the bar ("They're low in sugar, saturated fat, and cholesterol.", "packed full of the protein and complex carbohydrates your body needs") .
The ad also asked if they are late and if they have no time to eat.
Busy people don't usually have much time. ("Late for work? No time to eat?")
An ad that says information like this should be best for busy adults who care about health and nutrition.
