An advantage of using sports drinks for fluid replacement during exercise is that:

c. they have a pleasant taste which encourages consumption.

Explanation:

If you are doing moderate exercise in a very hot environment, you may also lose electrolytes that can't be replaced by drinking water alone. Sports drinks can help replenish electrolytes lost during exercise, and because they contain sugar, they can also give you a boost of energy to help you get through a workoutThe best bet for rehydration is to consume a low-cal beverage that contains electrolytes such as sodium and potassium.Good choices include sports drinks (go low-cal if your workout), try coconut water, or water with a slice of fruit. The refreshing hint of flavor may drive you to drink moreDuring exercise, the main way the body maintains optimal body temperature is by sweating. Heat is removed from the body when beads of sweat on the skin evaporate, resulting in a loss of body fluid.

Pretty bad i would assume.
