b).  one agent secures benefits that others pay for.

Explanation:

The free-rider problem is described as the problem when some individuals consume or take the benefit of a resource without paying for it. in this problem, one agent is being benefitted from the resources that the others are paying for. This creates a load on a shared resource and eventually causes market failure. In order to cope with this problem, the organizations must ensure a fair distribution of resources and their benefits as per the payment made by the agents. Therefore, option B is the correct answer.
