Answer:
The correct answer is letter "C": bans viewing by non-subscribers.
Step-by-step explanation:
In economics, the free-rider problem arises when individuals refuse to pay their fair share or pay less for something others are paying. This situation occurs when individuals can consume a given resource without limits and when there is regulation over the resource consumption.
Thus, Daleview is avoiding the free-rider problem in its TV cable service by setting bans to non-subscribers accounts.
